So this is a weird one! So first of all I have a 2013 with 63K, exhaust, cpe intake but no tune. No monkey business at all really, other than I beat the piss out of my car. However if you play inside Fords parameters it seems to be up for it. Anyway I have developed an odd issue with my waste gate actuator. After a peroid of use and under mid range boost maybe 8 psi or so, the waste gate starts actuating seemingly at random. So it is rapidly cycling boost in and out making a the car go Whaa whaa whaa. Then i chill out and drive the car gently to avoid inducing boost for a little while and it goes away. The phantom of the waste gate has slipped back to his layer for now. WTF? I put a new boost solenoid on it and no luck, we checked the waste gate with a pressure tester and it seems fine, it doesn't appear i have any boost leaks? Anybody else experience this? Any idea what this is? Any help is appreciated and this is the short story, I have alot more details however i dont think you guys want to read a novel so hit me up and ill share them.
