Did you notice any difference in performance or just rail pressure?

has anybody installed the super diesel modded regulator? Were there any noticeable gains to be had from it?

Sorry Dix, didnt see that you posted here. It holds rail pressure higher and longer. Big improvement on the top end. The idle is SLIGHTLY rough but not enough to even be concerned about. A stock Corvette idles rougher than my truck.

BTW- here are pics of the DMAX metering valve with the rectangular port. Also a pic of a modded gerotor plate.

Industrial Injection has just released a complete mod kit and Fleece Performance is working on releasing theirs very soon. Dont know anyone running the Super Diesel kit but I'm sure we will soon. :up2:

yes, the idle is rough, but completely fixable with EFI, when I first did mine I was pegging 21000psi rail at idle, but have since gotten it tuned down to 4900 psi at idle.

Mine really isnt that bad to me. Just slightly lopey so I've just left it alone. Its not adversely affecting performance or mileage so I'm good with it. Sounds kinda kewl actually. :up2:
