So I recently installed the zzperformance full exhaust on my 2013 sonic 1.8L hatchback with a hi flow secondary cat. The issue I'm running into is I'm running a solid bnr tune and when I install my weapon r cai system I get a cel code p0171. I know from the tune I'm on the richer side with fuel maps, is this intake to much airflow for the maf sensor to handle. I figured with the tune I'd be fine...I kept the intake on and reverted the sonic 1.8L to stock and drove for a bit then reflashed the ecu to the modified file and the cel p0171 code popped again, I kept the tuned file on the ecu and put the stock intake back on with the high flow panel filter and put the neg battery cable back on and the cel light never came on. I'm stumped...
