So I have stage 2 APR tune on my car, I put on the o2 spacer so I can pass inspection when I put the car back into stock tune. I was able to pass inspection the first time when I got the tune, now this time around I put the car into stock mode, check engine light went on, no biggie, drove for about 55 miles, all of a sudden my traction control said it was malfunctioning, my parking break, and my tire pressure sensor ( I think that was it, might have been more). I pulled over checked that all of those were fine and put it back into the APR tune hoping that the engine light and all of those sensors were going off just due to the stock tune.....I doubt that though, anyone have any idea? I have to get my friend's code reader tonight so I can see what is going on a little more.

If needed, I have:
K&N Typhoon Intake
Turbo back Neuspeed exhaust
