The Chip that keeps giving.
I have a Hummer H3 not Much at first the more I drove it started changing The tone Change I have Delta 50 flow master three inch in and out. The sound is Great. The shifting well improved I have the four speed automatic. Won't shift in four gear tell the temp goes to Normal Every time startup it get better
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
