that is making some badass power if that truck does infact weigh 5900lbs

 

Well my first couple were not so good.... In the 14's. That time was after having it on for a year and a bunch of tuning.....Also with stock 17's not the 20's. Now the tune is back at the begining after the intercooler, it threw off all the tables. The wieght of the sierra denali is what sucks, the Dana 60 rear end is heavy with all the quadrasteer crap on it, along with all the other options it adds up. I never would have thought it was that heavy either until my tranny guy suggested I get it wiegh after his lift struggled lifting it. ( compared to his 1/2 ton)

 

out if curiousity, what kind of gas mileage are you getting? or do you even keep track?

 

haha, well on the highway I can get 16.5 or so If I keep it around 65, anything above 70 its not very pretty. ( 4.10 Gears) In the city 11-12, average 13-14. Now these numbers are normal driving no WO runs, If I go WO it drops fast.

 

thats not horrible... im only getting 17-18 around 75, anything more and it drops bad. in the city im getting just as bad. and thats with a stock 5.3 in a 4400lb truck...

 

If I do 75 Ill get like 13 if I am lucky haha...
