did you get it tuned?

[landins13]

youve got huge injectors for that little ass turbo and if you arent tuned thats your problem

and if your "tune" involves an safc (or any piggy back setup for that matter) it's not really "tuned".

[ka-t_180sx]

no its not tuned

[FaLKoN240]

Have you TUNED it up?

Sparkplugs were my problem when I couldn't hit clean boost.

no its not tuned

there's your answer. get it tuned and im sure your car will run good. your ecu is stock means your motor is stock. upgrading injectors, turbo, cams and etc....means you need to get a tuned at a dyno with supported mods.
