EFI and a Predator for Quick checking . The EFI will log rail and data for later reading on the laptop or you can have real time data logging .
I have seen a new gauge from Di pricol that is a 30,000 psi rail gauge . I would like to look into this some more as it would be cool to see if it would work . It would be another asset in monitoring these engines.
I was reading about that on a Cummins forums somewhere, thought it might be a good idea when I finally get to doing some power mods. I haven't seen anything about except from the CTD boys.
There is a big difference from 22k to 26k . you will need dual fuelers for that but it is very noticeable even if you dont change a thing ! The top end is ridiculous on this tune with the duals and MITUSA !
Are you guys running a regulator?? I'm thinking about using a pump to push through a external fuel filter . so that I don't have to change the factory one very often.
Im running a holley blue w/o the regulator atm, I like the carter black better. Much quiter and performs well, neither pumps makes over 20 psi so you should be fine w/o a regulator.
I run A Holley HP150 with regulator. Its is OK. The Edlebrock 1792 is way nicer. I have one new in box to replace the Holley. I have a Wix version of the CAT 2micron fuel right after the pump. I made my own billet pickup with a return. I have not had any trouble with running my tank down low and I beleive the pickup is why. I also ran 10AN line from the pickup to right under the drivers seat.
