Really ? All the tunes out there are street tunes. A tune is a tune. Don't matter if it's street, track, 1/4 mile, 1/2 mile, or Nurburgring. IF anything they may tweak your 10R80.
get ahold of @Flyhalf
With the 10R80 4th & 5th have a distinct advantage over the MT82 by way of rev drop. 6R80 all gears are at a disadvantage to the MT82, except for first. Back to the 10R80 4th & 5th gear it's like 1300 rpm higher in the RPM band. I'd call that a huge A-D-V-A-N-T-A-G-E.
Absolutely. I raced a 14 GT500, VMP blower, TH400.. he kicked my arse. Haha. Goal for me is 10's NA, don't care where in the 10's, once done, a big ole centri is what I'm gonna get, then I'll run him again.
The coast side preload is out of spec. I installed a set of FORD PERFORMANCE 3.73 into my 8.8. I paid particular attention to the coast side. No noises for 3500 miles now. Tell whoever installed them to get it right.
Yeah me to, shit idle, shit drivability. 100 % blame on my tuner, Matt. He use to have his own business (that's when I got my tune), couldn't cut it and went to work at VMP, guess he couldn't cut it or got fired from there, now who knows where that bum is. Went to a known good backup tune.
