Bone stock 08 Denali, wife took it out of town yesterday and made 16.5 round trip.

Looking into some kind of tune for overall performance increase and possible fuel milage increase, any suggestions?????

I wish 16.5 in town, this was all out of highway driving.

Yeah but many dont realize where some people actually live. Driving in the city is stopping at a stop sign every 3 blocks or a red light every 6 blocks or aholes who dont look when crossing the street so you constantly on the brakes. Or when you actually get on the highway but then there is traffic and cannot go more then 45mph. Driving in these conditions you get 9-10 like clock work in the city and about 15 on the highway. BUT when I go upstate its wide open and I get 14 "in the city" and about 18 on the highway. It really depends on where you live....

I get about 12.5 avg half highway half city in mine. Its an 08 6.2 escalade. I have always wondered why they didnt make mine capable of using e-85. Not that I would use it but I see denali's all the time that have the badge on the back
