    Serious question please look PLEASE help me try to 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!!!

    Upgrade your fuel rails.

    There is a known issue with cylinder 3 not getting enough fuel due to the rail design. Boomba Racing fuel rails are just over $100, thats your fix.

    What do you mean by you really need a tune? You need a tune before you even drive that car.

    Trac light might be referring to it possibly trying to slow you down. You never know with computers now and days, they always have some type of countermeasure to when you're having issues.

    Also you did state that it happens during turns, so maybe its doing that due to you making a turn and traction shifting.

    Contact Boomba Racing first to make sure it will work with your Top Feed setup...I know it says WRX but you want to make sure if its for your application as well. You never know.

    You also might want to look into a phenomenon called "bore wash". With that much fuel being dumped I can guarantee it's happening to your motor. See if you can get a temporary map from your tuner that can get you safely to their shop.
