I have a wierd problem , well actually my PT GT has a wierd problem. I noticed it ever since I installed the AMX1397 CAI.
When I back off the gas to shift gears there a very loud and annoying fluttering sound. I thought it was the factory surge valve, but I installed the AGP blockoff plate and TurboXS BOV and the sound is still there! So I thought it might be the stock wastegate actuator and hoped the AGP wastegate actuator (for an SRT4) would eliminate it. But since the AGP actuator won't fit, I'm still stuck with the sound.
Does anyone have any idea what is causing the sound and what I can do to eliminate it?[:I]
FYI, my boost is great with a rock steady 15 psi at WOT and no surge or falloff.
HELP!![xx(]
