FG2XR6T New Member 7 Member For: 3y 8m 27d Posted 13/09/20 01:41 AM Share Posted 13/09/20 01:41 AM Have a question for the pro Tuners out there. In my adjustable options ( X4 ) I have - "Turbo Wastegate 40 percent" Currently set at 40 Percent. Not sure what this adjusts exactly. Any info would be greatly appreciated.

Generic tunes are garbage and destroy motors even in the form you purchased it at. Get a dyno tune and forget about ever needing to care about parameters on the X4.
