I've seen 0-60 5.3sec, 60' 2.13sec with COBB's Stage 1 OTS tune and their OEM+ TCM tune (I have the Corsa resonator delete but I don't think that gives any power boost). I was in 4A Sport and brake boosted but need to try it with traction disabled and diff locked. I think it has a little more in it on the 60' time. Conditions were 45'F at 1000ft with high humidity.
Very interesting. This pretty much confirms my suspicions that the Cobb tunes w/o the tranny tuning gave power on dyno but didn’t equate to much in terms of actual improvement in acceleration since the tranny was still acting on stock parameters. Your 0-60 #s WITH their trans tuning- which, no offense I’m just going to guess is no where near as dialed-in/complete as MPT/Gearhead for example- are behind the OPs & while respectable are basically about where a good stock run could be. I’m sure more repeatable w/ the other mods + tune.
Just to be clear- not knocking your tune/mods just stating that, essentially, I feel like cobb was selling “1/2 tunes” before & w/o any adjustment to the TCM didn’t really translate to tangible significant improvements in real world acceleration. I had called em out on this they refused to offer up any before/after 1/4 mile results & the results they did show w/ ECM tune only were nothing to write home about.
You’re def on right track to disable TC, but I think locking that rear might not be best idea on pavement while simultaneously going Wot balls to wall....
I’d love to see how the OPs draggy device compares to actual times @ the strip.
While I’m not really that concerned about running Baja trucks down the drag strip it’s cool to see how much a tune transforms these things. High 12’s in 1/4 from a 5600 lb flying brick on 35”s is just nuts.
