My car is currently doing the same thing. High RPM, full TPS signal, Full boost. Goes right back to normal if throttle is let up, but if RPM's are increased to same level again, same boost, same issue. I have never got it to cycle into overboost protection at all. I have tried with 12 PSI and 14 PSI with no change. I guess I could go lower....
Looks like it's time to call John....

Thanks, will do. I know it has damage to the connector from the PO. There is a funny story about it, and where I found the knock sensor bolted to. But I will save that for another day.

similar problem here but when I use less aggressive throttle modulation (read I dont just put the pedal to the floor) and let boost build up gradually I usually dont get any stuttering...also...I just failed inspection due to knocking...I related this to the 02 and cat..think these could be rlated in some way?
