My 07 black ltz is getting around 13.4mpg hwy and city combined. Anyway, when I had it the dealer for 6,000 service, I asked why mine was getting such bad mileage, truck sales mgr told me to tell tech to "recalibrate system that I should be gettin better". Service tech said he didn't have any calibrations from GMC - Has anybody heard of this?

| Looking for advise on a performance exhaust system. I am picking up my LTZ on Wednesday. I have already purchased a Cold Air Intake (CAI) system from Airaid hopping it will help the engine breather better, and thus burn less fuel. I turn 24k + miles per year. Now I would like to improve the exhaust. Not sure what top get, I read some of the earlier posts, however they all seam to concentrate on Noise/Tone/etc. That is not what I am looking for, I would like to keep the noise/tone as close as possible to OEM, however want the engine to breath better. I understand that one goes with the other, but there must be some compromise out there. Not too loud, but free flowing. Any help would be greatly appreciated. | |

Replying to: 2tahoes (Jul 08, 2006 3:44 pm)  I went to the dealership and they said the same thing. Recalibrate the DIC. which is the onboard computer. But when I went to service they had no idea what I was talking about. I think that the computer is not calibrated for the 20's even though they are stock. If you do some math with you fill ups you should be able to get your actual MPG. Min eis really about 13.4 MPG. The recalibration won't help one bit with MPG jus thow you computer calculates it. Does anyone else know of any computer reprograming that will help with the MPG?

Replying to: acmath (Jul 09, 2006 6:50 pm) As for the cargo area, I think I am going to get the Husky mat with the template for 3rd row cut outs. I like leaving my 3rd row in, but tumbled forward and I don't think CatchAll has something for that. And, I want that one to be rubber so when I go to the nursery for flowers, or my dogs get fur in there (gasp!!), I can just brush it off. I think carpet wouldn't be the ideal material for the cargo area. Good luck!! And have fun in your new Tahoe! |

Replying to: lapilotdude (Jul 07, 2006 6:44 am) At least it starts up at the same point that it was at when it cut off. I had an aftermarket DVD player installed by the dealership when I bought the 2003 Trailblazer, and it "forgot" where it was at any time power was cut. Talk about annoying! |
