I doubt it will run if you don't do anything else to change the fuel delivery. Sure, at idle it will be in closed loop mode and will constantly be trying to high stoich, but its can only compensate a certain amount. I would be willing to bet that you're way outside that amount. Figure out what size the stock injectors are and figure out what percentage you changed the inj size. Then dial back the SAFC low throttle map by that amount and I'd be willing to bet the car will run. A really crude way to do it would be to just turn the fuel pressure down until it runs, but thats not really a good idea.

i was told i dont have enuf pressure. and that the fuel is basicly leaking out since the injectores arent pressurized. also i dont have the safc tuned its all stock.
i heard the ecu is only sending the amount of fule to pressureize the stock injectors. sooo..... im just talking. anyhting else?
