2007 Silverado Question?

[Chip]

I get 19 mpg max on the highway with average 18.2. I don't do a lot of city stop and go driving.

I have a 6.0L in a 2007 2500HD and I love the truck but the mileage is killing me. Can anyone suggest a cheap or not so cheap performance chip that they've had some luck with. (present mileage 9 to 11 mpg on 2 lane mountain roads)

Any Ideas?????

I have the 2007 Silverado special order (dealer only) with the 6 litre modified 2005 Corvette small block. According to GM Vintage Vehicles Services they only made 166. I get 45 mpg highway with 800 lb load, 32 mpg hwy with 1200 lbs load but I haven't tested yet pulling a big trailer. I think mine was an experimentation. I can go across B.C. for as cheap as our 2004 Corolla car. Rivac in Vancouver.

New Question... I just bought a new 07 LTZ. Does anybody know of a way to turn off the auto locking feature that locks the doors when you shift from park? You have a choice of "at park" or "at speed" but no option to turn it off. I hate it. Please help!!!

Its on the main menu buttons by the odometer. I just turned mine off.

Anyone have a good source for Bedrail guards?
Also, I put a K&N filter in it. I can feel an increase in throttle response, but mileage dropped from 17 mpg to about 15.2! Ya, I'm taking it easy and not lead footing it. Any ideas? Too rich now?

Change the fuel Filter
