My 2004 Yukon Denali Ran a 15.1 @93 with e-fans and a 89 Wheatley tune. I think the truck is about 5900lbs? How much hp is the 6.0 making? Since that 15.1 run i have done a cold air intake, Corsa cat-back, and a new 93 Wheatley tune! The truck feels so good and runs so much stronger than the 15.1 run! Just wondering if i'm near the 400 mark?

 

I'm thinking maybe 385 at the crank tops (but I'm bad a guessing HP numbers lol)

 

A Yukon 1500 4wd has a curb weight of 5196
the XL is 5547

 

yeah i would guess 375-380, but of course not to the rears, what percentage driveline loss do they have?

 

I thought they were heavier than that? I had a Buick Rainer with the 5.3 and that thing was around 4700ish and the yukon is so much bigger. Any other thoughts?
