hello i own a 05 evo 8.

Things i noticed last night after starting up my car.

- very rough idle... sometimes it will just shut off. (putting noise)
- i noticed that when my turbo spools it sounds very diffrent(louder). and it feels like it lags now and i lose power.

things that i have done.

- i used fuel injector cleaner and it seemed to make the idle better just a little, but not really.
- turned down my boost controller... but its still peaking same.

do u guys have any idea what might be wrong? please help
