Read the warranty carefully.
It came with a broken tp sensor which I installed unknowingly. It worked, even with the broken sensor, for about a week. After that period the truck refused to shift out of first gear. I made it home and it refused to crank. Had to call a tow then had it worked on. After all that I found out the sensor they sent me was defective. Make sure this is a product you want to take a chance on.
Fitting took just under 2 hours. As soon as you start the engine you can hear a lower note and at around 2000rpm the engine now comes alive. The difference in torque in the low end is noticeable and for the price this is a must have first mod. Next will be the BBk throttle body which will give even more gain!
