Hello,

I just installed a heavily ported 13B into my otherwise stock 3rd gen, and was wondering if I would still have to put in a new ECU if I add an exhaust / intake. I know it is deadly to run a 13b lean, so I don't want to risk adding more air into the engine if not enough fuel is going in. I figured the porting would bring in more fuel anyway (to balance more airflow from exhaust / intake), so perhaps a new ECU would not be needed.

Also, I live in mass., so any upgrades I do have to pass emissions

(its already passed with the ported motor)

Any help is greatly appreciated.
