I am sorry for your luck.

I recently installed a Steeda CAI and got a Bama tune after about 30 kilometers of driving with it I decided not to datalog anything I took the tune out, bought a Airaid intake that requires no tune. put the stock tune in it and listed my tuner and steeda CAI on local classifieds.

My bama tune was ok, but its because of issues like this I decided to remove it.

My advice is to get a SCT X4, and get someone who can tune it live to do it.

With how complex the Ti-VCT is thats the only thing I would trust.

Now don't ever go WOT with your car until you get a proper tune or return it to stock or you will be forking out 6500+ for a new engine.

Hey OP why don't you call JLT as well and see if there was a problem in production with that intake tube ...its a long shot .

I would bet that JLT will tell the OP to pound sand. They never admit to their products having issues

 

If it were me, I'd return it to stock. Not many tuners support the Diablo line on our cars, most are using SCT stuff. The CAI is not worth it on an otherwise stock car. For those two reasons, go back to stock.

Now, is the A/F measured with a sample tube at the exhaust or from a pid?

 

I am guessing he is using the PID

 

Hey Marc, might a Kam reset be worth a try, I had a rough idle too and did a Kam reset and all is good,

 

I'm assuming that was done on the last tune update. But if it wasn't done, it needs it.

 

Many people and tuners have bad luck with jlt stuff. The location of the maf for the jlt intake is shitty and gives a poor signal. So in that case, take it off!

 

+1 +1 +1. The design is **** in general. See where the halves of the carbon fiber meet? Directly over the MAF mount, I'm not saying yours is leaking there, but on the plastic JLT tubes, there is a giant valley at that exact spot that causes an intake leak at the MAF.

I'm done with JLT, had issues with their CAI and MULTIPLE issues with their catch can. They refused to finally fix the can and claimed the CAI had no issues. The catch can was also causing a bad vacuum leak. Combine the two and I was 20% lean at idle.

After having surging issues at 70mph with the JLT CAI with both Bama and HMP, I swapped over to an Airaid. No surging issues and no vacuum leaks whatsoever.

Well I don't have 5.0 but a 4.6 with a JLT series 3 and a Bama V2 tune w/o issues

Apples to Oranges. Their stuff for the 4.6's was decent. Their quality fell sharply for the 5.0.

Lol Funny because that's basically what they told me with the catch can issue.

Looking closer at OP's pics, that tube looks like plastic with a C/F overlay on the out side......

Without being able to see one in person I couldn't say for certain.

But if that's the case.......what a ripoff.

There also shouldn't be seam unless it's just a bit of gelcoat....which I doubt.

With all of the carbon fiber/kevlar I've laid up I've never had a seam like that...

 

I read on C&L's website that they recommend the maf sensor should be 6-8 inches from filter and within I straight line from opening due to turbulence from bends and velocity factors., it seems like it is very close to filter, like 3 or 4 inches

I'm building my own intake and after speaking with Jon Lund and another guru they agree on two things, one of which I just mentioned and to not put to close to throttle body as well.

 

Well I don't have 5.0 but a 4.6 with a JLT series 3 and a Bama V2 tune w/o issues

 

I had a Steeda and I have an airaid and both have velocity stacks and I don't think JLT does.

I think the velocity stack really helps with smoothing the air out.

 

Thanks for the feedback, all.

Even AmericanMuscle.com themselves say that the JLT does not come with a reducer insert so I find it odd that with all the supposed in-house testing that they claim to do, that I would still experience so many severe problems after installation.

Fortunately my car is not a daily driver and I currently have it parked for the week while waiting for Bama to write me a new tune.

My plan of attack is to upload the new tune this week and drive the car to my dyno shop (unfortunately it's an hour away in NH). I'll have them throw it on the dyno and make a couple easy passes just to see what kind of A/F I'm looking at. If it's not flawless I'll purchase an SCT tuner from them and have them write a custom tune and seek a full refund from AM. I should hope that with the car sitting on the dyno and an SCT X4 in hand, that they'll be able to write something safe yet powerful even with the JLT intake. I was expecting to see 380-390 at the wheels, 325 is unacceptable. Not withstanding the idle, stalling, and check engine light issues.

I just hope I haven't done any damage to the car by running it with this garbage tune. The oil temp gauge hasn't gone past midway and the check engine light/limp mode only engaged once - does anyone think that I've already caused permanent damage?

EDIT: The A/F ratio was measured at the dyno shop with a pipe in the tailpipe. There was also a connection under the hood but I'm not exactly sure what it was - I'm no mechanic.

 

It's hard to say about damage. Without physically having the car in front of me anyway.

But I just went back and looked at your op. 325? I know it's a different dyno on a different day in a different area of the nation, but my car out down 377 stock with a 1500 mile break in. I would expect a tuned car to at least do 400.

Go ahead and say it guys- dyno numbers are :blah

 

You could always have Bama send you a tune for the stock air box and switch back to that.

 

Hey OP why don't you call JLT as well and see if there was a problem in production with that intake tube ...its a long shot .

 

Hey Boston,

First I want to apologize that you’re having issues. I know how that can be as a fellow Coyote owner who has installed aftermarket parts that have caused a hiccup and had to reinstall, modify or replace to get it running perfectly again. Either way, we’ll take good care of you as our customer!

Looking through the issues that you’re having, there’s likely something going on with the intake and we want to help get it squared away. We’ll work with you to replace it with JLT or any other intake that you’d like and then get the Bama team to update your tunes to match and you can work with Bama’s Lead Calibrator in order to datalog and make sure that it’s running spot-on! I have no doubts that between replacing the intake and getting that fix verified by datalogging with Bama, they’ll have you rowing gears in no time!

That being said, JLT does make a quality product and their intakes have been performing well for years on everything from V6’s and GT’s to Cobra’s and GT500’s with huge blowers. There have definitely been surging issues with this intake and we’ve run into it before, so it’s apparent something is wrong and we’ll work with the team at JLT to try and get it solved once and for all. They’re great people over at JLT and will always work hard to put out quality product and fix any quirks.

In the meantime, we stand behind every product that we sell and our customers, so you can always shoot me over a PM and I’ll gladly take care of you guys.

-Will

 

I just ordered a JLT and SCTX4 this morning from AM and hearing stuff like above makes me nervous. I know AM is a stand up company but I only have 2300 miles on my 2014 GT and sure don't want to hurt it.

 

Hey bodon,

I don't think you have anything to worry about! We will make sure you are 100% happy with whatever you purchased and we will get you car shredding tires ASAP!

If you ever need anything, you know where to find me.

-Will

 

Hope your car isn't an auto....

 

Yes it is. You know when I went on AM's website I had one of their Online techs help me. I told him I wanted the best and he steered me to a JLT unit. Don't see why they would do that if there are many issues with JLT.

 

I'm not a fan of the JLT intakes at all... I went from a really nice Steeda CAI when I was N/A, and the MAF mounted in a piece of billeted aluminum perfection perfectly to this crappy JLT that comes with the VMP Stage 2 Kit.

The JLT feels cheaply made, but what most irked me was that the plastic hole for the MAF didn't even fit the MAF correctly. I had to use a metal file to file the plastic down on each side so that it was actually flush so I could fully insert the MAF. Luckily that worked fine and it's snug in there, but I really wish there were more CAI options for TVS applications... I'd go back to something that's metal on MAF any day if there was an option.

Sounds like AM is gonna take care of you, but I'll mention I have the Steeda for sale cheap buried in the classifieds here still.

I hear ya. I've had nothing but issues with my JLT intake for my TVS, absolute garbage. "improper installation" JLT claims. junk junk junk

 

The problem with auto cars and the JLTs, is the pcm uses MAF signals for shifting the Trans. The Jlt cai has been proven time and again it has the dirtiest MAF signal, and the PCM doesn't like it.

At least you've got their new tuner guru to help out.

 

Weird hearing about all these problems. I've never once had a problem with my JLT...knock on wood...and its an auto:hidinghere:. What other brand has been proven to produce the most power and best driveability on the auto?

 

Same issues with JLT/SCT X4 from AM

I have JLT CAI and SCT X4 BAMA tune with the same issues. I have had two tunes with the same results. The guys over at BAMA blew me off and told me it was too bad that I was disappointed with my purchase. They instructed me to Data Log the car and send results in. Feels weird to pay for a good "Custom Tune" and have to do leg work after they get my Mastercard number. Then I wait 2-days (not including weekends) to have a specialist look at results and send new tune if it logs the required info. They told me that they deal with a thousand customers a week and this is their reason for the delay in turn around. Its really too bad that we have to deal with these situations when we have spent so much money and receive little to no results or service. I will probably try the data log and cross my fingers that the car is good enough to drive until I get the "Fixed Tune".

Curious as to exactly what problems you were experiencing. Havent put mine on yet.

 

My Experience

When I first start the car it sounds like I have .956" lift cams in the thing. First time I heard it I thought my car was going to go down the street with its knuckles dragging. Idle smooths out after 30 seconds of the car trying to find the idle RPM range going up and down. It then goes to a normal idle, but then when you take off it will try to stall out on me. Sometimes its so bad I have to push the clutch in to avoid the embarrassment. Once I get it rolling the car will go into three stages of surging acceleration with the same amount of pressure on the pedal.
Stage 1= The little train that could..... I think I can
Stage 2= Normal
Stage 3= Get the Hell out of my way!
Pretty embarrassing in parking lots and stop lights, because it looks like I've never driven a stick before. It usually does the 3 stage surging acceleration threw the first 3 gears and goes away until 6th. Then its like riding a Bronco and trying to hold on for the full 8 seconds. Serious bucking. Usually I will avoid 6th until the car gets to normal operating temperatures. After that the car kind of settles down through all gears, but the first three still have acceleration surging. And if you act now you can have all this for the small fee of $629.99 and remember shipping is always free.

Damn dude that doesn't sound very bueno. On the reverse side of things, I thought the Bama Tune with the Steeda CAI was great when I was N/A... never had any issues with hesitation, stalling, or anything like that. Amazing how much difference just the CAI makes.

 

I have great esp. Wanna see?

I'll bet one of the AM reps will be in trying to straighten this out.

 

Like Walmart

 

Nah! Like I said earlier, I called and got the old "thank you for your purchase, but please remember to exit through the gift shop". I've spent a lot of money at American Muscle in the past 2-3 months, and I guess I expected a little more customer service than what I have received.

 

Well at least I didnt break the shifter or something. Could you imagine how embarrassing that would be........ Oh wait.... Too soon?

 

Lmao, true that!

 

Airaid or Steeda

 

lol look Marc hit the nail on the head.
