New member here! On our second flex. We are having a surging issue, wastegate releasing boost i imagine due to code it’s throwing. Wondering if the cat has anything to do with it? Have replaced the boost solenoid and no change. Hoping someone has had or helped someone with similar issues. Thanks all!!



assuming the hoses to the solenoid are properly secured, you can check

a) the blowoff valve for torn gasket
b) the turbo actuator c-clip for excessive play
c) the turbo piping for cracks esp near/at the clamps

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
