This is my first foray into Tuning, but with this product, and a little research its point and click. Installation/use was easy, and tunes can be modded as you go. Easy to read, easy to navigate, easy to use (to a certain point, for a novice). And fun. You notice the differences in performance right away.

Easy to set up. Easy to program vehicle. Better acceleration; better power; some increase in MPG. Almost like having a new truck.

TruXedo TruXport Roll-Up Tonneau Cover Reviews

Fourth TruXedo in five years!

Reviewed By Marc A P (Malone, NY) Reviewed for a 2003 GMC Sierra —2/18/2015 2:45 AM

I own a fleet of GMC 2500HD snow plow trucks and have added the TruXedo Roll-Up Tonneau Cover to all four trucks. I am very happy with the ease of installation, as well as the look and the fact the covers keep 100% of the snow and ice out of the truck box. Excellent cover. I highly recommend this product.
