I just purchased a hypertech III power programmer for my 97 Z71 with 33x12.50 tires and a 3inch rancho lift kit the programmer was great to recalibrate the speedo and what not but as far as adding power and torque im still looking for it a month later i felt no power gain so i took it to a dyno and before i put it on i was pushing around 280HP after was 285HP and 378.00 dollars later so if you want more power dont buy a hypertech tuner instead go to westers pcm tuning there pcm are the best in the business they cost more but after i got mine i said hypertech whats that

thanks,
Josh
