I can only speak about the c5 2002, and I was only able to get the loaded tune from diablo. No adjustments for my car at all. I sent mine back , good luck

My 2010 honda civic averaged about 37-39 mpg on freeway going 75. I noticed a great increase in torque and acceleration. The responsiveness was a lot better too

I think you would need to go up a size..That car is much bigger than my Corvette..

Anytime you increase horsepower in an engine you stand to abuse the tranny, rear-end, and tires along with everything else in the suspension. It really depends on your personal driving habits. If it's a Ford 7.3 you're driving, I saw a terrific increase in power with my 96 F350 with the 100 HP kick. A WHOLE LOT OF FUN. Would have liked to have seen better mileage but only have a single 4 inch exhaust out. My drive habits did not see an increase in mileage if not lost some. A friend of mine drives a 2001 or 2 Ford Exabition with this programmer and has increased his mileage 20-25%.

Can't speak on 4.0 but my 3.8 (08) it made a huge difference! Shifting problems were solved. Better acceleration and highway speeds. Definitely made a better vehicle to drive.

Yes, the less restrictive design helps the engine run smoother and more efficiently. I'm not sure how much of a difference, but it will help.

Yes right away, took a little time for the computer to re a just. But with a Aem cold air intake and the headers, now it's like a sports car!

MPG down a bit but better since adjusting. Imstalled on 72 ghia. 1600 stock engine. The boost in performance is massive.

You will sacrafice fuel milage, mine went from 42 mpg to 38 mpg. But worth it to me. I've made mods to the engine and changed exhaust 2 or 3 times and the Auto-tune keeps it running at peak performance. No more costly dyno after mods!

My 95 Integra/Acura had done 200,000km before I replaced mine.Fuel economy was really bad driving normally after a full tune,replacing all filters,leads,plugs etc.Replaced O2 sensor and had vastly improved economy straight away.My RPM"s were normal. Mine had no check engine light come on.Dont forget to reset CPU. Still have car as its so reliable.Best of Luck.

I don't think this improves too speed, but you will feel a differance in the upper rpms and you will get better gas mileage.

I have noticed some level of difference but was not much. Best tune for my 2009 jku is 87 octane. And I was able to make some adjustments to s ok me things like fix my speedo for larger tires, make lights come ok NE at certain times. It has features besides the performance. If you seek performance only .....not sure how significant it will be in your case.

Hey if I turn my my performance all the way up. Will I need other upgraded parts like thermostats.

The intercooler itself will not increase power. You can actually have a power loss if using the factory turbo. You will also notice an increase in lag over the factory top mount by 200-300rpm. Once installed, you will need to have th veiicle tuned in order for it to run properly.

Probably not. The main reason people buy these for performance is that they have rev limit adjustments and are far more reliable and consistent than the original equipment in 30-50 year old cars. In a relatively modern vehicle with with an ECU (Computer) I doubt you would see much improvement.

I have the 6.0 and it helped. Its no dragster but improvement across the board.

None, after running it for a while, what fealt like a gain was not, dyno showed same results a a drop in performance filter. Also mileage dropped, to 25 mpg from 29 mpg. I recently returned car back to stock, power is the same, fuel economy back up. Only positive thing about this unit is price, and sound. I had the Mopar unit, prior to this, and a K&N; as well, money wise, lesson learned just buy a K&N; replacement filter and save some time and money. On a side note if you are looking for bling and nice tone from engine, then the unit is worth it.
