Cubes, I got my turbo 2 afm pipe on with my stocker blocked for the moment with no atmo BOV and it has a catch can installed.
I get backfiring, etc, but its a combination of my 02 sensor dead (reads like 0.02v at idle and randomly goes to 0.30 and then back to 0v while driving) and I have all those mods on stock ecu.
