this is just a 25-30 roll on my denali from awhile back...finally got it uploaded so im postin it up...mods on the truck in the vid is BorlaXr-1 and Tune by rgvsierra
on OEM 20's...truck still has cats so only mods is rep. muffler and tune....feel free to criticize lol...best time from the denali i've gotten is 13.7@100mph on Tune,CAI,Borla

heres a pic...

hoping to get some kooks LT's maybe and probably 226/226 from patriot? maybe a 228/228 still debating though...

 

am i missing something? you ran a 13.7 on a tune and exhaust alone?

 

13.7 (tunebyrgvsierra,BorlaXr-1 w/cats, and K&N intake) the vid i only had exhaust and tune but my times were on the mods listed in sig/^

 

hmmmm 13.7 with a tune,exhaust,cai on a crewcab..... i might need to see that to believe it....if thats true i should drive my truck off a cliff!

 

the Denali has the 6.2,they are strong

 

plz have someone take pics otw off the cliff then

 

well excuse my smart *** coments then....props to you....thats impressive. those new motors must be putting out some crazy power!

 

great times dude and sweet pull

 

I did a 13.8 on my 2000 rcsb 5.3L, fully bolt on, tune, 4:10s
stock torque converter and stock cam..

Hes got a lot heavier truck but its a 6.2L, and if not mistaken those babies come out with 403HP.
Very credable E.T.

just my .02 cents

 

Sounds good!
