I'm only adding a few bolt on items to the truck. Vent visors, oval tubes, mudflaps, under seat storage tray, and I just ordered a Rough Country 2" leveling kit for the front  Nate |
I'm averaging only 11.5mpg with my '13 GMC SEIRREA SLT. A ways off from the sticker of 17mpg. Considering Headers w/High Flow Cats. made a difference with my 2005 GTO, almost 2mpg and 28HP at wheels. Anyone in here know if this would be the same with the LQ block compared to my LS in the GTO?
