OK..I was talking to a long lost buddy and he was saying that I can replace my filter with an aftermarket one and a chip to increase 4-5 more mpg to my 07 Yukon. I know with proper tuning (with knowledge and equipment) one can do a whole lot....I will be replacing my stock filter with a K&N filter...however, is there such a chip available for the 07 Yukon?
Thanks.
