420A Resistor box ?

[Inkdlyfe]

Alright so I'm planning on turboing my car again here soon but how would I tell what injector is bad and how would I tell if my resistor box is bad ??

What do I need to get inorder to not have to run a resistor ??

Literally took me 2 mins. The search tool would have saved you time over starting a new thread.

Ok so I get how to clean and test them but I didn't get the answer to the other do I need the resistor box for the injector or no ? And what could I get or do to delete it. I seen something bout the plug and being cut but I got a factory harness which isn't cut

Low impedance injectors need a resistor box.

High impedance injectors do not.

If you get high impedance injectors (aka high Z) you don't need the resistor pack. Stock 420As come with high z injectors. Some one must have put low z injectors in it and that's why they need the resistor box.

Low z injectors typically cost less which is why people go with them. look at FIC's website for more info on low vs high z.

So running high boost it's better or worse high or low

Doesn't matter it's more of a tuning thing.
