I had it fry 3 times now on me. 1st time right out the hole. 2nd time it lasted maybe a week. 3rd time 2 days. It was awesome when it worked but at this point it's just been a teaser.

Nice product, BUT it's not plug & play. You have to cut wires and butt connect two and splice into two more! NOT PLUG & PLAY. Need a better wireing harness that makes more sense.It will take you a little more time then what they say!
no plug and play

i bought this product thinking it was a plug and play type install. well its not plug and play at all. you have to crawl under your truck unhook a plug on top of your trans cut 1 wire and splice into another how is that plug and play??? they didn't give me enough wire to reach the plug even when i mounted the box on the firewall so i had to extend it. i called customer service and they were no help, there exact words just find a 5 volt power scource under your hood somwhere and tap into it, wtf??? i wouldn't recommend this product to anyone

This module has insanely awesome RAW horsepower gains, puts no extra strain on the motor but gives some AWESOME results, a little harder to install than the instructions let on, but overall, TOTALLY AWESOME!!!!!!!!!!!!!
