I just purchased a 2006 2500, mega cab auto, 36k on it, the truck is totally stock right now (ill post pics soon). My question is that im only getting around 15mpg with this and im keeping the shifts under 2k, is this normal for a stock truck to get that mileage? Also if so I am just about to purchase some aftermarket stuff for it I was gonna go with the Airaid intake kit, and a silverline exhaust. I also have a question about that should I go with one from the turbo back or will i not notice a difference from the cat back? And as monitor wise i was thinking the quadzilla, adrenaline model. Sorry to bug you guys with these questions but as it says I am a NewB and would like as much input from all of you as possible

Thanks

might want to check with the dealer, and see if it has the latest re-flash. there was a tsb for poor mph, white smoke, cold start issues, on the '06's.

 

Thanks much appreciated that could def. be it.

 

U listed it as an automatic so how are u controllin when it shifts unless your shifting by hand?
