Best deal I could find for this product. Product performs great and I couldn't love it any more.

Item shipped immediately. Really like the compact design. Shows lots of customization information about my Duramax. Intead of windshield mount I used a shot ram mount with ball to attach to the driver grab handle. Mounts out of the way but easy to see.

i entered the 93 octane tune into my 2011 GMC Sierra along with a K&N air intake system, and I felt an immediate change in performance. the truck responds to the throttle much better, and I'm getting 2.5 more miles to the gallon.
