Well I didn't start this thread to discuss to tune or not. This thread is basically just a reference point on MPGs related to my current tune. Others may want to go this route, if so great, if not then great. I don't have issues with my current tune. In fact the truck has never driven this good. If one thinks that a gas tune is like a diesel tune, its really not. U get some HP and Tq but mostly just eliminates some of the TQ management. Diesel is another ball game, some tune way past the point of safe... which causes devastation very quickly when running hard. A Black bear gas tune wont do that, everything is in parameters. If the thread is going in a direction of debate to tune or not then it can be locked. That was not my intent to discuss it, simply just relaying info.
