just writing in to say that I installed my programmed pcm last night and what a difference. Alot better throttle response and now I wont be afraid to pass people on the highway. I will have to check out the milage to see if it got any better. I had it programmed for 89 octane, and shift firmness 2. Thanks again to the guys at pcmforless.:thx

Make sure you're done playing before checking for a MPG increase.:D
