help with injector sizing.
Ok so i have the turbonetics kit for the 02-03 spec v and the injectors it came with are 680cc injectors, but iam getting problems of fuel just getting dumped into the motor. i got the reflash and bought an safc2 but the safc2 cant take enough fuel out. so the guy at the dyno says we can try smaller injectors, or the AEM fic and he will be able to tune it. i know where i can get a set of 2002 stock wrx injectors. they are 420cc its only an 8lb kit will these injectors work? or will it be too lean under boost. its a stock motor, i am just getting a full 3 inch exhaust put on. If anyone could please help me i would appreciate it thanks

no i never messed with the FPR. turbonetics says the injectors in it or 65lb which is about 680cc. they are just dumping fuel the car runs a 12:1 afr at idle, and thats with -50% on the safc2

yes, the wrx injectors are good for over 300hp.
I HIGHLY doubt you will max them out on your current setup.
