Just curious ben were you running your own tuning then or someone else's?
My own tuning...this was 3 years ago though, a lot has changed since then. Single stock CP3 and regulator, stock motor, stock injectors. Just KD lift pumps, BD turbo, exhaust, intake, and an old-school suncoast IV. 7,600lb crew cab...
Is your converter locking when its supposed to?? That caused a lot of problems for me...
