For almost 2 months my Stage was working perfectly. Great boost, great accelleration, and the toys were all working as specified. Then over the course of a few days, things started to deteriorate. My car started boosting above the 20 mark and the dial-a-boost levels I had become used to changed. Where setting 0 was originally 9-10 PSI, it was now 14-15. Setting '1' had also raised to 18-20 where it was originally 15-16. Setting '2' or '3' were spiking past 20 and the needle fluctuated something fierce.
Pretty soon, none of my settings were working and to put it simply, I had to be careful with my right foot. WOT would shoot the needle straight down. (25+ PSI?) Also I had the trouble where my pink line on the WGA would pop off. I finally got that held down tight and upon the next spike I had another hose pop off and I lost much of my braking.
I have since changed back to the original Wastegate thinking that was the problem. It no longer boosts past 18, which I assume is because the stock one isn't strong enough.
I'm at a loss for what to check next. Calls to the Mopar helpline haven't helped and I haven't had time to take it to the dealer, I need the car as a daily driver.
It sounds like to me that little or even none of the boost pressure is actually reaching your wga. Perhaps a hose is broken, disconnected or leaking very badly. Trace down the pressure source from the wga back to your turbo and verify all the hoses are intact.
