I dont believe in power chips and computer reprogrammers because gm knew what they were doing when they built the car. I hate aftermarket crap because its all cheap and unreliable. The only thing that my car will have on it aftermarket when im done with my car will be a flowmaster at the most. I like that stock appearance too.

 

my car which i'm pretty sure has stock gearing does about 2600, 2700rpm's at 80. when u hit 90 thats when you get close to 3000
