I have the exact same truck as the OP. Going to the track tomorrow night, only mod is a tune from Geoff at EPS. I was expecting around the same time as slowfive0 just a mph or two higher. I'm in south Louisiana though so may get a slightly better time.

 

Not sure what DA was on the day that I got 12.9 secs. But temp was 55 degrees. I was running a lil more than 6Lbs of boost and AIR FUEL was 12.5 during the run. IAT was maybe 75 degrees at the start of the run. I also switched from 4wd to 2wd as soon as I got off the line.

 

My buddys 014 denali 6.2 plug n play maggy beat me by a truck length against my 014 tuned 6.2

 

DAM impressive,is it track? driver? incredible ET stock,makes me rethink modding my 014 and go 016 with 6.2 NHT and starting there

 

I personally think a tune would make a big difference. I "hear" these are too rich and obviously the torque management. Another degree or two of timing, little leaner, get rid of a lot of that torque management and the truck should pick up nicely. I'm betting at least 3 tenths and 2-4 mph. Did you end up running it?


Interesting. From the two times I've been to the track, I would guess (not knowing DA for you) my truck would run 13.90's at 97-98 on same day. Obviously guessing. What mph did you run again on that day? What was your 60 foot?


Definitely, not the track lol! Being able to leave in 4wd pretty much negates any issues from different tracks. My old truck which was must faster didn't care where it was either. These trucks launch awesome---love 4wd or Awd :-D

Definitely, not me lol. I'm doing the right things I believe to obtain a good time, but a lighter person would go even faster (I weigh 300). I was really hoping I'd get that high 30 degree day before the track shut down. I'd have to think the truck would go faster. Maybe 13.60's.....13.599999? I don't know but would have been awesome. That said, what would the truck do with a couple of light bolt ons and a tune? Can't wait to see some peoples results! Also, have any of you guys heard whether the aftermarket cat back exhaust systems gain anything? I have the stock "quiet" exhaust and would like to keep it, but very curious if there is anything to be gained.

I think the 8spd helps slightly but not sure it's worth upgrading just yet. What's the improvement over a 6 speed truck??? Not sure. Maybe a tenth? Maybe a few hundreths??? Not sure. A buddy here has my exact truck (Denali and everything) but it's a '14 with the 6 spd. We were supposed to race to compare, but he couldn't make it that day Plus, he got a '16 to replace it (last week) so that race will never happen now.

 

Sure did. 13.800@99.48 going again this Friday with catback, intake and no spare. That's the most weight reduction I'll do since it basically just makes up for me being a fat *** haha.

 

I will be surprised if the ET gets better,hey just my OP,better weather will help
