Love my Jet PCM. If adjusting the transmission shift timing was the only adjustment, it would be more than worth the purchase.Typical of all Chevy's, my truck shifted hard. Well, not anymore, it shifts so smooth now that most of the time I can't tell when it shifts. Absolutely awesome. I installed a K&N Cold Air Intake and MagnaFlow Exhaust System. I could feel the additional HP with each performance part. It has really made my Chevy a joy to drive.
