The IDM is like an amp for a sound system. The more the amp puts out the better the sound. The IDm drives the injectors and this mod basically turns up the voltage to the injectors.

I have read anywhere from 20hp 60lb to 60hp 100lb regardless though there is a deffinate increase that you can feel.:woot:

Im not sure this has been discussed before, and a search brought me too many unrelated posts to sift through SO.
ONE. Will this mod work with a chip, or does the chip negate the benefit of it?

TWO. If it DOES compliment a chip, is it worth doing to an 03?

Yes it will work with a chip. No a chip does not negate the benefit of it. Think of this mod like a sound system: the amp (IDM) drives the speakers (injectors) a chip changes timing, etc like the head unit contols bass level, treble etc.
Essentially the injectors push the fuel harder..so better atomization, combustion IF anyone has any more input they are welcome to chime in at any time

From what I have read, No this mod is not hard on the truck. No it is not hard to do. AS LONG AS YOU FOLLOW THE INSTRUCTIONS YOU SHOULDN'T HAVE ANY PROBLEMS.:rockon:

Your truck has an IDM 120 an OBS has a IDM 100. The IDM mod essentially makes them all into IDM 130's so you be the judge.

99's (early and late) can have either an IDM 110 or IDM 120.

IDM 110's take the same resistor as the OBS IDM 100 does.

You'll have to pull down the inner fender and look at it to be for sure. It should be listed on the sticker right where the harness plugs into the IDM. If this doesn't make sense look at the pics in the instructions

the 7th pic down should give you a good visual
