fg turbo boost error
Fg xr6t manual, stock turbo and flapper/actuator, full 4" exhaust, cooler etc, closed loop boost control.
Its getting an occasional boost cut closing throttle on the street in higher gears with a boost error of less than -1psi before cut, tried both overboost threshold and overboost threshold B doubled to -4psi, same. I had thought it would need to be a boost error greater than 4psi over desired to cut with -4psi overboost threshold.
Is there another multiplier im missing?
There are overboost threshold and overboost threshold B, whats the difference between the two?
Thanks

over boost thresholds will set an over boost condition when error is LESS than in the box.
set it to 0 and max the P1227 threshold and timer
