Easy to install!
The quality of this product is great. Instruction was very easy to follow. Noticed 3 mpg better on the city. I actually got 4 mpg better on the highway. Definitely notice the quicker response on throttle body and definitely noticed the HP gained. Not exactly sure how many HP at the Wheels. Goo products and recommend to buy.
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
