Would 310cc injectors be to small to run 7-8 psi on a stock motor or would dsm 450 injectors be preferred
I dono man, I'd chock that up to the AEM, I ALWAYS had idle issues with that fucking thing. I'm running rc 1000's with a resistor box and it idles beautifully, even with the stage 3 cam. I'm not using a driver, either. According to Jeff, with my setup, a driver would be ulitmately useless. The drivers on the newer ecu's are plenty efficient to handle a p&h injector with not problems. I've had the injectors for about 6 months or so and haven't had any issues with them. I know alot of k series guys run them without drivers, as well...If its a D17 dont use DSM injectors. Dont use low resistanc peak and hold injectors without a standalone and I would strondly push an injector driver as well. Even with the resistor box its not the way to go. I ran DSM 450s on my AEM ems and they idled awefull no matter what anyone did to the maps. If you look around more there are other injector options on the table.
