Well I completely rebuilt intake/all new vacuum lines J-boot, dist. cap, rotor etc. Still flutters...so it was down to the wastegate. Or was it...
I installed new lindsey dual port waste gate and ... Still flutters.
She idles better, my boost (when all warmed up) is more steady and over all, she runs better.
I did notice in playing with my boost, that at 3/4 throttle there was NO FLUTTER !!! I just replaced the TPS a couple of months ago (trying to figure this out then too), so I have a hard time believing that it is bad. I will call Lindsey and ask if there is a chance I got a remanufactured TPS...
No way, right???
The only thing I haven't replaced is my AFM, and my fuel lines.
Anyway "still frustrated"
