I bought this tuner to fix the slow shifting in my Tahoe, and gain some power for towing. I am very happy with this tuner. Currently running with the 87 octane tune and tweeked shift points. My truck has a lot more power and has even gained fuel economy around town. Originally I was at 13/15.5, first installed an Airaid intake kit (Highly Recomended!) improved to 14.2/17, now with the tuner- 15/17. But the best part is in the little adjustments that can be made. Adjusting the shift quickness and pressure for each gear in standard and tow/haul mode individually. Changing RPM and MPH shift limits. After adjusting little by little my truck drives perfectly. And it takes less than 5 minutes to reprogram.
