Do you have a O2 clamp. Pm Olderguy, he makes them, tell him what your car is doing, he could tell you if it will fix it.

We are running into the same situation as far as bogging. Low RPMs is good, flat on the floor after 4000rpms is fine. The transition to boost is bogging on our car.

I got to find the O2 clamp, and put it on.

Olderguy would be good to talk to.

Well it looks like my wideband o2 decided to start displaying a wideband signal to the factory ECU. Everything my car was doing is starting to make sense. Something went screwy in between the new firmware flash and recalibration. :bang:

I'm going to get a bung welded into my downpipe for the wideband and use it strictly for tuning and not use the simulated narrowband output. I'll leave the ECU signals up to the narrowband o2.

Thanks for everyone's input.
