I went with a few buddies and the diesels to the track this morning. My best run of the day was my first ran 15.14 with a 2.2 60' , 89.9 mph. I was pretty impressed with only a 91 Livernois tune, last year stock it ran 16.1 so that's a big improvement.

The other trucks
05 Cummins , intake, 5" turbo back exaust, chip 15.5
04 duramax, chip, turbo back, intake and some other thing, went 15.1 also.
2011 duramax, efi live , turbo back exaust, intake, 14.7
07 jeep 5.7 hemi, exaust, intake, Diablo sport tuner, 16.6

Pretty good day at the with my buddies, I'm hoping with full exaust, intake will get me around 14.7

Do you have a lift and huge tires? No offense but I would drive my truck into the wall if I ran 15.1 tuned with everything else stock. Just joking of course, full exhaust will get you a couple mph. Those diesels should be faster too. I ran a 14.4 in my 05 dodge diesel tune only.

Which track? Sounds like ya'll were at least a mile high to run those times! LOL

vic_s197

It's in denven so it is a mile high lol cars tend to run 1 to 1.3 seconds slower up here, and I'm running bigger tires 275/65/20 I'm happy with the times

I was talking to a guy that just moved here from California, his 2012 5.0 mustang ran 12.8 over there, and up here today he ran 14.4 lol he was pissed

Altitude affects n/a engines more than f/I engines. Picking up a second and half with a tune only is pretty nice.

Altitude sucks. I'm spoiled to sea level. A second gain is very impressive though.

Yea it sucks up here but what can u do. Those diesels didn't see me coming lol they were impressed it was tune only and was running faster then all of them minus 1
