Hi everyone.

I have a 2010 Audi S3(8P) manual. I have fitted a downpipe. (76mm), CAI, forge DV and stage 2 software. The car has an erratic idle and the agents can't seem to find the problem. We have replaced the PCV valve, the low pressure fuel sensor, the throttle valve MAF Sensor and the problem still persists.

Has anyone experienced this and what have you done to solve it? Please help. I'm at my ends with this. It's quite annoying to drive the car like that. Also the car is slightly down on power.
