Couple more questions? When my car is low on gas it can jump up to a half tank or more when im going on a curvy road making it impossible for me to tell how much gas i have. Do they all do that? Also is there any drawback to leaving the performance shift on? Like does it decrease your gas mileage significantly during normal driving? I have to say the only thing im not overly impressed about the gtp is the transmission. Will a aftermarket pcm make a big difference? I think im going to buy one from intense racing unless someone else make a better product but they are the only site I have looked at so far.
