i have a 2002 subaru wrx with 90k miles.
list of mods.
turbo xs front mount intercooler,
cobb accessport v2,
20 gauge turbo,
My car got out of the shop about a week ago from getting a 20g turbo put in. i got the car back and everything was going well, boost was steady, ran clean and strong. I was testing out the power of the new turbo (taking it easy) and all of a sudden i get a stutter and the car starts misfiring. 5 check engine codes, 1,2,3, and 4 cylinder misfire, and system running lean. At this point in time i was running stock injectors and figured it was stuttering because it wasent getting enough fuel. so i installed 800cc high flow injectors with a 20g turbo setup. the call still continues to misfire after injectors were installed. got a custom tune and that still dident help. can anyone help me with this? i just spend 2 grand on turbo and injectors and now this! any idea? oh and i changed spark plugs 2 times gaped them 3 times to .28-.30 and nothing..
