5.3 L gas mileage and power increases
Okay, new area, now I can ask. Has anybody had any success increasing the gas mileage out of their 5.3 Liter? Also, anything that helped with HP increase too? Got an 02 Yukon and would like to get better MPG and HP if possible.

not a whole lot you can do about this one as far as MPG . mine has a single flowmaster 40 series (one 3in inlet and 2 2.5in outlets) with dual tips ran out the back, and the k and n FIPK kit but i only noticed a small difference out on the interstate on long trips(more miles between gas stops) and it seems like nothing around town. hope this helps...........joe
