The experience i had on the website was great. Order process easy. Great communication. If i would recommend changing anything it would be the way they package exhaust pipes.

Just got this today and setting it up was so easy. I have ordered from another company but had to return twice but the quality of this product is amazing, screen is well lit, and it is an amazing tuner.

Bought a full kit for my 2017 Ram 2500 and everything fit perfect. The hangers lined up right and the truck sounds amazing. Took about 4 hours to install, but most of that time was spent taking old heavy exhaust off

Absolutely amazing. Second kit I’ve ordered from Tuner Depot, super simple install if you are mechanically inclined. Loads of power and switch between tunes on the fly.
