Secondary cat is gone. I bought an accessport from OpenFlash since Cobb discontinued its accessport for the BRZ and I tuned it but the CEL pinged yesterday with the same code. I'm not sure what the problem is as the person who tuned it for me said everything looked good. When I'm low in RPMs, especially at low speed, there is a delay/stutter and I can't push the pedal down all the way or I'll just stall. If anyone can help me out it'd be appreciated and I'll provide any additional info you need.

Do a log where this happen.
I assume your K&N CAI threw your MAF-Calibration off. Put the Stock Intake back on and give it a try.
