Hey guys a friend is having issues tuning his FG turbo. The car has been converted to external gate. When ramping it up on the dyno its closing the throttle and throws the code p1227, waste gate control system failed. When converting to external gate do all the tables relating to the factory turbocharger control have to be zeroed out? Would having them still in the tune cause this issue? Another FG f6 (retaining the factory turbo system) is also throwing this code too.
Have attached a copy of the tune. Any help would be appreciated.
Thanks!
