Can anyone tell me if the '08 Denali's 6.2 has active fuel management? How about the '07's? I would like to find a recent Denali but really don't want AFM. Thanks.

 

It might be quicker to just call your local dealer up and ask the sales manager.

 

I was at the dealer last week and they didnt have any Sierra Danali's for 2008 Only the Tahoe's. I even looked thew the catalog and didnt find them. But I do know you can get a tune to turn it off.

 

Thanks guys, I had thought someone here might know, I tried a local dealer but was unfortunate enough to get a very uninformed salesman. I will try again. So what turns it off rxsteven, is it just a software program?

 

This is were I want to get my tune. If you email them im sure they will give you all the details and answer any questions you would have. For a mail order tune they send you a new computer for youre truck with the tune already on it and then you send them youre old one back.
