on the fence about hypertech
2012 5.7 hemi charger. Keep getting random misfire code. Unplugged hypertech cleared code put 50 miles on car no code. Called hypertech sent it in and they sent me another. Came code. Called hypertech they said they didn't know and they would replace it again or for me to return for refund. Product made power and torque if you dont mind your check engine light being on all the time.
Dissapointed, but has a use for some
It took my top end and put it down low, increased drive ability far as not downshifting and torque in higher than you have to be gears, but at wot in lowest gear lost top end, actually took .75 sec off 0 to 60, if you tow or have big tires and don't race, an could trade top end speed for low end torque it's for you, not for speed addicts. Low end mid range torque was very noticable but made truck overall slower
