Ok, little history:
2003 Cobra with KB 2.2, Bassani Exhaust, about 20lbs of boost, pretty conservative tune (this will be getting redone soon). Just bought the car, runs great but got the dreaded P0193 code and car would fall on its face. Replaced the FRPS and then would have the same thing happen sometime later. Checked the FRPS and it wasn't blown. But after doing some research on here, seems there could be an issue and why some people go to the return fuel system (definitely going to do that) and why some people do the PPRV delete. Car has the KB BAP, supposedly has GT pumps. I looked in the trunk where the BAP is installed and it doesn't seem to have the FPDM mod to it. I guess I'm going to have to verify the pumps and FPDM some how.
Either way, was running fine. Well, now the car is just having issues only under boost. First, it started as a part throttle, light boost issue where it was acting like the fuel was cutting out. Watching the Aeroforce gauge and FP Gauge, didn't see anything funny. But now it's doing it under boost at anytime. Only thing I noticed really strange was the Duty Cycle was bouncing all over the place.
I know my EGR is probably filthy (have a new on in box waiting or I'll just delete it before I go get a new tune in the Fall). I get the following codes in my X3: P16A8 (can't find that one anywhere) P00B0 (Supercharger Boost Control B Module Performance (WTF is that?) P0193 (verified the FRPS isn't torn by putting it on a vacuum at 15" over night with no loss and no gas in the vacuum line) and the infamous P0405. No idle issues, no drivability issues when not in boost.
So....any ideas? Like I said, the car is new to me and I'm just going to have to start "tearing" into things to start finding out what exactly has been done compared to what was supposedly done. It's clean and ran great, but I think everything that was done was done awhile ago and the owners in-between rarely drove it and none of the items were kept up (such as vacuum hoses, etc) and we all know how rubber parts react to time.
