    and i rate it -10 out of 10. i got this thing for my 04 silverado 2500hd 6.0 and no matter what i do ever since i installed it engine tumbles at only 4-500 rpm and dies if i put it in drive. so unless hypertech has a quick fix over the phone, they will be paying for my ecu to be flashed. i haven't seen a single disclaimer anywhere.

    Do not buy this.
  2. Does it tumble after removing the hypertech tune? Hypertech does have a 30 day return policy.

    Thats interesting. about a month after i programmed my rig with a hypertech programmer my transmission went out. The mechanic who rebuilt my tranny said that the programmer had nothing to do with it but im not so sure it didnt.
