I just put on this http://store.knfilte...px?Prod=57-3058 on Thursday and after about 200 miles, I can tell a difference. The response is quicker and seems to run a lil bit better! I can't really answer about mpg because I have been punching it hard since. But my kit is for an 08 sierra denali and I don't know if its the same as yours!

I understand the pros and where you coming from with having a 4x4! But its not a biggie with me and my lifestyle! If I was a outdoors-man,I mean a TRUE one then yes, I would have one or one just for hunting or fishing! I like trucks because I like the room in them while you drive. I mean these new truck are comfortable. The worst part about having a truck is, when people move for one place to another, they ALWAYS want touse your truck or help them move with your truck! I hate that!

People buy 2x4 truck because thats what they want! Or, like me, they may not ever get off the pavement! I don't like how they sit! I don't like lifts or leveling! But I like trucks!

I have a 08 SD with the L92 and it's kick@$$! I've nevered towed with it, but street race, and won plenty!

Wanna line up?!

So all in all, both motors should perform similar?

I have an 08 sierra denali with a 6.2. The SD in 07 also had the 6.2. The Denali/SUV/Caddy was the only truck to have the 6.2 until 2010 I think. Is it the L9H motor? No, it's a L92 truck engine that came stock in the Denali from 07-08 i know for sure. And it don't have AFM.

Any difference between the new 6.2 and say 07-10 6.2?
