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

I had to call tech support who walked me through it all. It took one hour to install. Configuring took time due to me learning while configuring. The gas pedal is a lot more responsive with no hesitation whatsoever. There's a noticeable increase in horsepower and the exhaust system sounds better. I don't care for the design of the unit. It looks cheap. More computer options would be nice. It's pricey but I like the performance. I'd recommend it !!!
