Did you have trouble with the PY06s or did you just want to update the look of the wheels? You mentioned an ECM upgrade and I was curious what you would gain from that. I'll bet that it is a very nice truck to drive with the comfort, power, and ride feel.

I appreciate the comments.

Rear wheel spacers are Stahl brand, made out of steel. Stahl is the heavy duty division of Bora brand spacers. Bora's are considered the best in the industry. No issues with the PY0s, I wanted the rear track to be as wide as the front.

Blackbear did the tune on this one. It improves fuel and timing maps, shift points, removes torque management(if wanted), etc. Mine drives extremely well and has made 13.6mpg running down the interstate at 73mph, fully loaded down with family and gear. For comparison, my 2011 1500 Suburban with a 5.3l would only get around 14.4mpg in the same instances, and it had far less towing capacity and comfort. (it was tuned and had worked exhaust as well)
