Default Injectors, peak & hold or saturated?

What's the difference, and which do I need?

With the factory ECU driving the injectors you will use Saturated, high impediance injectors.

EMS runs them fine. If you go with the other you will need a resistor box.

ooooh got it. injectors will be ordered.

I called ASP, steel pulley's can be ready in 3-4 days, aluminum pulleys are 3-4 weeks! I might order mine from vortech.

So you need saturated high impedance injectors for the EMS?
I'll have to go and check which ones I have at home..

chairman, I'm talking about the injectors I bought used to use in conjunction with my EMS. (I haven't installed them yet)

oh , I thought you had some extra for sale.

I'll be placing my order, and waiting 3-4 weeks for the pulley

With the EMS or even the stock ECU, you will need an injector driver box or resistor box if you go over 750cc injectors with the RC's. 750's are the largest you can go with as a saturated injector.

If you go with a saturated injector, you can just plug them straight into the wiring harness, if you go with a peak and hold, you will need a driver box or resistor box wired in.
