IDM mod. Does it work?

I couldn't remember either ( all that clean living in my youth) so I had to look it up.
Injector Driver Module
The solenoid-operated poppet valve requires 115 volts at up to 8 amps to operate, which is more power than the PCM can supply. Therefore, a high power device, the Injector Driver Module, is used to supply power to the solenoid on command from the PCM.
The sticker on the IDM will identify it. IDM-100, 110 or 120.
It's an IDM-120 on my '01

If you have a IDM-110 it might be worth a go. I just called a buddy who has a late '99 and his is IDM-120 also. Maybe the early '99 used the IDM-110.
IDM's are indeed pricey, and tuners/chips are a really an easy no brainer install. I'd leave the IDM alone personally. I agree with Clux that $700 buys a lot of tunes.

It absolutely does work.....especially if you have aftermarket injectors. Almost all of the "hotrod" PSD's you see on the boards and in magazines et.al. run 140v. IDM's. It's just that in most cases they did the mod so long ago they don't even remember to list it as a mod.
Way back when I got to ride in a truck with a switched 120/140 IDM, so I know it makes a difference...but I had never been willing to experiment on my own expensive part, nor had it been high enough on my mod list to pay the premium for somebody else to do it.
That is about to change however....last weekend I scored a 95 F-superduty IDM. As soon as my resistors come in I'll be doing a 140 conversion on it for my truck. So I'll have more better first hand for ya'.
