So I was considering putting adding the JLT Tuned CAI to my 2006 mustang v6. I was wondering if I can use a tune that runs off regular gas. Will this help gas mileage? and will it still increase HP? Is this a good Tuner and CAI to get?

Thanks in advance!

ps: Can anyone explain to me what each custom tune does? Thanks!

All CAI are basically the albeit an ebay CAI or one from AM. You're basically just paying for the brand name lol. For your Tuner questions, there are 4 Octanes and 3 different tunes you can choose from.

Street
Performance
Race.

For these tunes you can choose from 87, 89, 91, 93 octane fuel. You'll see a small, but noticeable gain from that mod but you will notice the most if your car is an Automatic as it changes shift points for harder quicker shifts.

Here is a more in depth answer from AM.

Street (87-93 octane) - the street tune is designed as a daily driver program that focuses in on increasing mid-range power. It does give up a few HP at higher RPMs, but that's why there is a Performance file. Automatic vehicles are further enhanced by making adjustments to the transmission's shift points and firmness.

Performance (87-93 octane) - The Performance program is designed to add power at 3000 RPMs and higher, focusing more on the top end horsepower and all out performance driving. Timing, fuel and throttle response settings are slightly more aggressive than the street tune. This is a great track tune but also works well for daily drivers that are looking for a little more "get up and go" than the street tune. The automatic transmission settings are the same as in the street tune.

Race (91 - 93 octane) - The race tune will ensure the largest increase in vehicle performance. Using the highest grade of fuel available in your area is mandatory. This file is designed for "Race only Use" as the timing, fuel, and throttle response settings are very aggressive. in fact, the adjustments are so aggressive, that we do not recommend it for daily driving as it may cause your vehicle to try to jump out from a stop and easily spin the tires. Finally, with the automatics, we implement entirely new shift points and firmness settings to further enhance the all-out performance of the vehicle.

yeah my cars a manual. i plan on adding dual exhaust after. but for now this. so is it possible to run a tune with 87 octane. that either helps or keeps the same mpg, but adds hp?

[mcqueen]

Matt pretty much has it right, except since you have an S197 you don't really have the option of using the cheap CAIs like SN95s and NEs do. You'll see better gains from your CAI and tuner than those of us with older vehicles would. More that likely you will not increase your mpg. If you drive sensibly you'll be able to keep your gas mileage where it is, but get a lead foot and you'll start losing mpg.

And yes, you can get a tune for 87 octane.

[D-Reck]

okay, and whats s197, im new and don't know too much about this. And it looks like i should go with the Street Tune do you think? or Performance, I need to stay with regular. So the main thing i don't want to mess with is the mpg, it either has to stay the same or increase. And i would like to have an increase in HP.

and when it says timing and fuel are more agressive in the performance tune, does that mean, it uses more fuel?

Yes it's possible to run an 87 Octane tune. You could always run 87 for your Performance tune as a DD , But as McQueen stated, it won't make your MPG's gain any. S197 is your body style of Mustang. Like Fox Body, 94-98 is SN95 99-04 is SN95 New Edge.

I'm running my 91 Race tune right now and my god does it suck the gas down

S197 refers to 05+ Mustangs. New Edges are 99-04s and SN95s are 94-98s. And yes, that means it will use more fuel.

Lol before my engine seized I was getting 18-20mpg on an 87 economy tune (economy might be old school, I've had the tune since Bama started with AM). With a 93 race tune I actually got slightly better gas mileage, although I only filled up with the highest quality fuel instead of whatever was closest when I needed gas. If you aren't already, try running Shell fuel. It's pretty good stuff And if you step up to a 93 tune, Shell's 93 octane is the only fuel I've found in a very long time that doesn't contain ethanol

[RedDevilGT]

I can't find 93 anywhere around here, so I just went with the 91 Race tune. :/

[D-Reck]

Okay i appreciate the advice. Also how can you find out the mpg, there isnt any like info button in my mustang, because i was trying to figure it out

[RedDevilGT]

Reset your Trip Odometer, then divide the size of your gas tank by how many miles you went on a tank of gas. I'm not too familiar with the S197's so I couldn't tell you if you had that button or not

[SON1C]

i run and have only run the 87 performance tune, dont know if street gets better mpg, but performance works for me

[D-Reck]

btw, is there a reason nobody with 05-09's actually reply to the threads in the 05-09 section?

[RedDevilGT]

It's not as active as the regular V6 Forum lol

[mcqueen]

Yeah, unfortunately we don't have a lot of active S197 V6 members that participate in tech discussions. I think the 2011+ section is actually more active
