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.

before you can understand whats it means you really need to understand boost control.

this information is documented everywhere online, start somewhere like here.

 

 

so then you take that into consideration

 

your actuator set for a desired boost level. anywhere from 4.5 to 9psi on the std ford actuators.

then 40 percent is your electronic bleed-off.

so if you have a 4.5psi actuator and 40 percent bleed - IN THEROY your getting (4.5psi+1.8psi) 6.3psi.

there is about a million things that will affect this, so it wont be cut and dry like doing the math.

pro tip, dont play with it.

Wastegate percentage doesn't even come close to the full story with regard to how much boost you could make. 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.
