Hey everyone. Had a customer bring in an old suburban running a L94 engine with a LSA blower with L94 tb, LS3 slot maf, Corvette throttle pedal, T42 TCM with a 4l80 trans. The calibration it was flashed with was an express van from 2009. Issue is the second you go WOT goes to limp mode p0600 code so it's a TAC calibration issue. What car/truck OS will work for this combo?
