Eric tuned my 68 vgt perfect the first round with no tweaks. No dead spots, no surging, shifting is spot on (for xtreme x at least.) RCD has the tunes for it figured at as well. I've had zero issues with the 68 and my 190's so far. really fun street setup with plenty of balls if you need it.
thats pretty good! for what im seeing, i see any were from 690-740 depending on the wind with stock injectors and stock turbo. do you tow at all or is it just a for funzys truck?
