I have a  2001 1.8t gti with a stage 2 tune with a 3 inch ccalled downpipe. I was straight piped with stock exhaust diameter peaking at 21/22psi. I got a 2.25 inch MagnaFlow glass pack muffler(10425) to quiet the car down as it was too loud and now the car is misfiring above 15psi when cold.  When  the engine warms up the misfiring isn't as severe(no longer throwing me forward)  however the car seems to be restricted.  The boost Gauge reads 18-20psi however it struggled to accelerate. There are no misfire codes but there is a fuel trim code and an o2 sensor code. The o2 sensor is tuned out and I believe that is why those codes are up.  If someone can tune my car with the backpressure and tune out my engine code for the o2 sensor I will pay you. I have a vag cable so I would be able to log for you.

Likely unrelated to your exhaust.

Okay I managed to log in VCDS lite for you. I will try ME7Logger in a bit if I can get it to recognise the cable.

Those logs don't have any important (usable) information. In addition, VCDS sampling rate is too low for your particular ecu, and important variables are not available for logging.

Is my cable not supported? It works fine with VCDS but not with other programs.

No, get ME7L working or sell the car.

Also, post the actual codes.

Yikes, you invited me over to your house and I poured soda on your carpet.  Ordinarily you'd just have to get rid of the entire carpet, maybe even sell the house...
