I just got a Diablo Sport Preditor Tuner for my 02 tahoe and tried it out at the race track. It made a huge difference in how it shifts with adjustments. Last year the hoe went 16.83 @ 79mph and after installing 1.8 roller rockers and this tuner it went 16.30 @ 85mph. Does anyone have more experience or comments with this programmer?
