Hi does anyone know where i can purchase a stronger motor or a shop to install one for my gen2? About 13psi of boost the blades wont open and im assuming the boost is over powering the motors. At 8 psi all is good so it relates to air holding them down some how.

Have the throttle-by-wire opening tables in the ECU been adjusted?

How do you know they are not opening all the way, are you logging the TPS signal?
