I absolutely love it! It's like driving a whole new car. The new throttle response is unbelievable. The only think I didn't like is when throttling down if you touch the gas to soon the car will jerk
I like it. I like the fact that it doesn't affect the warranty (because I had the dealership install it for $70). Maybe you are not concerned about warranty issues (if the vehicle has high miles, for example). The low end torque is much improved, the throttle is crisper (no lag), and the dashpot (engine braking) is much improved.
The disadvantage of the Pro-Cal tune is that it does not have an option for a CAI nor can it been adjusted for a bigger MAF or the Boss intake. If you intend to get the best out of your engine and you are willing to take some risk, you can tune the car yourself with SCT's ProRacer package. I used the PRP on my '98GT and I loved the way the car drove (if I do say so myself, lol).
The frrp tune is really good and as mentioned prior, does not affect warranty. Not as aggressive as others, but here is the warranty. Very good throttle response and can definitely feel the performance difference in the low to mid range.
Ok, thanks for the reply. I would definitely like the increase in low end torque. I would purchase a SCT tuner but i bought the extended warranty and don't want to void it. I don't race my car so all out performance is not an issue for me. I just noticed when i bought the car that it didn't have the bottom end that i thought it should have. I don't rev my car over 4 grand very often. So i would like an increase down low.
Then you'll like this tune. It makes the 5.0 feel like a V8 and it boosts mileage massively. Mine went up around 3-4 mpg city over stock. my car's ridonculusly funny with 3.73s, MT and this tune. I can pretty much hole shot anything that's 2WD. 0-60 is a wee tick over 4 seconds. Best 1/4 so far is a 12.60 on 7 year old drag radials, at 112 mph. There's an 11 (or at least really close to it) on a good tire, good day, full weight, in my car, I know it.
