recomend an injector size please

Its my Nova in signature.
5.3L Turbo with the 42# injectors on 15psi i had the injectors at 160% and the car didnt pull much.

So i switched it to 5psi and the injectors ran at around 80%. Ran good.
this was on a stock cam.

Im now putting in a 224/224 .581/.581 112 cam and want to run 15psi
what size should I buy? what kind are better?

And does the factory PCM run on high or low impedence? Im running the factory PCM w/ 2 bar HP tuner SD.

Thanks.

get atleast 60#'s high impedence....if you need to go bigger you need to get low impedence injectors which require a resistor box to switch from high impedence to low.
