My friend has an SRT 8 charger and is constantly going on about a diablo tuner he wants to get that is apparently so amazing and awesome it will somehow bring his 380 rwhp to 500 rwhp. I'm pretty sure he's full of crap on that, but I am wondering if there is a tuner out there that would make my car a little faster.

I have a completely stock 97 mustang gt.

Also, completely unrelated, but I read a post on here where a guy said a lightweight flywheel was the best part he ever put on his car, as it lets him rev up so much faster. What is considered lightweight? I see everything from 26-12 pounds. Is 26 lighter than stock, or is it just a shiney stock replacement?

Dude, I saw that guys post about the flywheel and my head turned like a confused dog. I mean yea it will make some difference but I could see no possibly way for any human to notice the difference in a lighter fly wheel. all it's there for is to start the motor and connect the crank shaft to the torque converter. Honestly I think he was being sarcastic. As far as chips, not too sure if there really what they say but look on ebay. They have some for like 30 bucks or something that say they give you 10-20 hp. And as far as tuning your car......bro...it's completely stock. I mean yea there are probably some different air/fuel ratios they've came up with that may increase power a little but nothing major. Save some money, do it right, and get some bolt ons or go for the PI swap man.

380hp to 500hp from just a tune is complete b.s (unless a diesel truck is what he means)
a good tuner for your car would be either a sct handheld or a diablo predetor tuner. most likely the gains will be around 25hp on the performance tune. it all depends on what mods you have to determine how well your car reacts to a tune.
and as far as light weight flywheels go, basically just get an aluminum one from like SPEC and youre good to go

Good to know about about the flywheel, after reading the other post I was thinking about ordering one. haha. I didn't think the tuner would do much if anything to a stock car. I've heard they're more for making the mods work well together, but on the off chance my friend wasn't full of crap I had to ask.

i got 29 hp from the JET performance chip, im not sure what it would give a stock car, but on the plus side, install it into pcm and forget about it. no controller or wires

I recently put a predator on a 300c and it made a big difference, but not that much. There is doc. of them getting 35rwhp and another 40rwhp on top of that witha dyno tune. Make sure he gets the pc adapter withit, b/c he can't use it eith out updating the firmware first. And lightweight flywheels make a diff. b/c it is rotaing mass= more hp to the asphalt.

Been in the game for 10 years now and i never understand were people come up with this stuff. No way you will gain 100+hp in just a tune unless its a diesel lol

You couldn't be more wrong. First of all a flexplate connects to a torque converter.

Second, the crank connects to the flywheel/flexplate, which holds your clutch/torque converter, which connects to the input shaft of your transmission. Then the knee bone connects to the shin bone and so on.

Also, there is away to notice a difference. There's alot more to it than "I installed a new wing and I can feel more down force at 55 mph"

Here's a basic example that you can expiriement at home with. Take a 12 pound bowling ball in your hand and spin in circles. Now take a 5 pound bowlin ball in your hand and spin in a circle.

Its easier to spin, no? Less rotating mass = less momentum needed to achieve higher speeds. Thus a lighter flywheel will spin up the engine faster. Same reason why all of those awesome race cars use aluminum and fiber drive shafts.

Only thing to remember is that when you get lighter, it's because you're taking material away. That means when you start pushing high power numbers (If that's your goal) you could run the risk of breaking your flywheel.

yes but were talking about on a car, which is a lot different than a human being. does it make a difference? ehhhh maybe but it definetly ISNT the best mod someone has ever done unless theyve done NO other mods.

start out with something basic instead of going right into the engine/tranny

A chip may net you 20hp TOPS.

Iv heard from many tuners that our cars (96-98) just dont make that much power especially in stock form and you cant really tune them to make alot while stock.


Do something legit and then worry about a tune. Supercharger/turbo/ nitrous/cams or something interesting
