I installed a cold air intake, high-flow throttle body, and performance exhaust in my Grand Am, but without proper tuning it's quarter mile time dropped by half a second. This PCM did a good job of bringing it back to good times.
Decent power Good buy, 1.10.2007

I installed this item 3 days ago and the power increase is slightly noticeable the shift points are definitely better, I would recommend this product if you are upgrading the exhaust and intake also.
