Just ran a 15.077 @89.80 with a 2.194 60 ft. on an 87 tune. It was sunny and about 65*. I could actually hook this time and droped 7 tenths! The only changes from last fall are a bully dog shift kit, G80 (needs clutches), 265's and 2" leveling kit. I weighted in at 6315 on the tracks scales after this run. I was really hoping to break into the 14's after this run but couldn't.

60' 2.194
330' 6.283
660' 9.660 @ 72.96
1000' 12.580
1320' 15.077 @ 89.80

 

Congrats on the good run.

 

Man, if you wouldn't have eaten lunch you could have broken into the 14s. That's close!

 

Sitll had the tail gate, tool box full of stuff and a buddies full nitrous bottle with me. Probably could have dropped 150-200lbs. I also forgot to clamp my springs. I didn't expect to run that fast or else i would have to break into 14s.

 

Your tune might need some help. Your 60 is great for such a heavy truck, but then you slow down from there. Not much but I think I was 14.8 with a 2.1 60' but you are making more hp because my 6.0 was stock at the time. There for if you are getting off the line good you should be faster at the top end.
