paulr33 Posted January 5, 2008 Share Posted January 5, 2008 with the actuator disconnected, the wastegate will never open, which means boost will continue to rise as long as the throttle is open and the engine is ingesting air this basically means your running unlimited boost - be careful with this - it might go bang. what spring are u using in the actuator? what boost controller have u got setup? what exhaust setup do you have? have you checked the actuator / swing valve for play? does the wastegate flap actually open?

The spring on the actuator is factory kkr, exhaust 3inch after market turbo back. i have checked the actuator it functions fine, tryed with 2 diffrent boost controllers one electric the other just a cheap t piece style same resault. i have also tryed with no boost controller does anyone no the least boost you can run with this actuator?? so wastegate hole is to small thats my problem?
