L92 MPG's w/ bolt-ons & towing cam?
What MPG improvements you guys are seeing in L92's with truck cams and headers? So far, all I have is a tune, and the gas is absolutely killing me. 13 on the highway at best, and about 11 in town..... and it's a short wheel base Yukon.

My L92 got 20mpg highway on a 5000 mile road trip last year. Only mods at that point was a tune.
City? Ehhh, 11 - 13mpg.
I just put on long tube headers but haven't received my wideband to tune with so no reliable data for you there.
