Will a stock ecu be able to handle a good sized steet port? Any side effects?

 

you mean stock remapped ecu as in M2, pettit, etc yes they will run a street port fine

 

I mean for my N/A? Does any one even modify the stock ecu for second gens, besides superchips or md racing (or something like that)?

as long as its a "street port" it should be alright. im not sure how big your talking about though. i think that if youve got the port and maybe intake and a full exhaust sytem then its about time for bigger injectors and fuel stuff though
