help me fix this cel so i cn get TUNED!!!!

i have a 08 sti with a 20g 850cc injectors aem intake, catless exhaust etc. my problem keeps happening where i keep getting a p0303 misfire cylinder 3, traction control comes on, and defaults to s mode. now i have swapped coils it has brand new plus and injectors in it, and has good compression. it happen to me twice after making a hard turn and boosting right out of it, all of the lights came on at the same time. i almost know its not in cylinder 3 idk is it possible that the traction control light is some how causing the CEL and the cylinder to misfire, maybe fuel cut off, it only cyl 3 that it keeps happening too?? please help because i really need a tune!!!

Your misfire CEL is most likely from not being tuned.....

Are you really running all that stuff untuned?

Its safety for the car. If you didnt revert to limp or safe mode and kept letting it misfire in the cylinder you can go ahead and count on rebuilding your engine. Get the tune and talk to your tuner about it as they could/should be able to see the car in person and help more.

Who is your tuner? I'd be shocked if they couldn't fix the problem before it got tuned. I believe if the CEL comes up 3 times the ECU will freeze frame "snap shot" the exact thing that is causing the CEL. Making the tuner's job a lot easier to troubleshoot. That is what my tuner said when I was have a CEL last year. I can't remember what he was using some kind of scan tool for the laptop.
