Wish I had more to add but I have more questions than stats... My '11 4x4 rcsb 5.3/6l80 3.42 is a complete dog.. especially on the hwy.. Have you guys been happy with your tunes? Are you keeping the afm? Pulling a 2klb trailer last week it stayed in between 4th and 5th and had me at 3k rpm. 7mpg on that trip. Ouch.

 

so far ive hit a 14.6 with my 09 CC silverado with full exhaust, headers, and tune, added a stall and intake so might make a trip to the track this weekend to see if i can get a low 14 pass.

 

im getting ready to go to the track friday as long as the temperature is high enough for the track to open. i posted my mods on new member forum under lets go to heartland park. my 2012 had 3.42s but i just got 4.10s. with a decent 60ft. time i should be setting a mark to beat with stock longblock!

 

May 18-19th I'm taking mine to the track. 11.80's will make my day.

 

13.797@98.85mph with a 2.084 60ft 1/8 was 8.883@80.25mph

 

Sorry if I missed this somewhere but was that with your gears and cam? Or without those but with the rest of the stuff in your profile?

Very nice run!

 

everything but the cam. stock 2012 vvt/dod cam.

 

going back out on 5/10
