Inyectors or Fuel Pump My car is running the inyectors at 119% on NO2 and at 90% on motor.
RWHP is 365 on motor and 450 on NO2.
My question is, should I change the Inyectors or the Fuel Pump, some people say Inyector should be enought, other people say go for the fuel pump. If I change the fuel pump the inyector will go back to normal.
I would like to do just one for now because of cash issues, so what would it be the right one to do.
Also if I go with the Inyectors, which LBS inyectors should I go for. I know to get the SVOs but not sure on the size.
Thanks

Danny, you may be ok with just changing the injectors. The Duty cycle is not going to go down with just a new fuel pump, that will only go down with new injectors. I'd say get a nice set of 30lb Svo witch are about 36lb at our fuel pressure . I bit the bullet and changed out my fuel pump and injectors just to be safe...I didn't want to risk running lean and losing another motor

Need more info. Are you running a dry shot or wet shot? If you are running a dry shot that you probably want to upgrade the injectors. If wet, probably not. How much nitrous are you running? 100 shot? 150 shot?

Also depends on where your fuel pressure is at at WOT. Injector cycle does not mean **** if your pump can not keep up. Are you going lean on a WOT run or just seeing the duty go up? Lots of things to consider for the fuel system. )2 injectors should be good for 450-475rwhp
