I think with the right programming it will do decent if it is in good shape, mine will not keep up with my stage 1's with a super chips tuner, but like i said in stage 1's and smaller, ie tranny savers, I think programming and using the oil wisely has alot to do with it.

I was told by a injector tech at DPP (diesel performance plus) that a stock HPOP that is in good shape should support most stage 2 injectors. The stage 2 injectors I was looking at were 180cc single shots if that helps any. They were to replace my stock split shot injectors in my 02 F350. He did mention that because I was changing from split shots to single shots custom tuning would be required to run the injectors properly. He also reccomended that I install fuel and oil pressure gauges prior to the new injector installation.

as long as your not constantly playing with the new found power it will keep up just fine.for the first couple weeks your gonna set the CEL for the P1211 code many many many times cuz you are gonna play with it .

in order for you to upgrade your HPOP since yours is a 94 you will need to read this http://www.superdutydiesel.com/forums/showthread.php?t=4833

one thing to take into consideration when chooseing injectors is that alot of the guys,myself included,that got stage 1s ended up either wishing they got stage 2s or like i did and went up to the stage 2s

The OP has an OBS which has a smaller HPOP than the SDs. It won't support stage 2's very well. No way a good early HPOP could hold 2400psi for very long on an aggressive tune.


BTW....2400psi is nothing....you should feel what 3150psi at the blip of the throttle is like, even on stock SD sticks!:ZigBang:

you think 3150PSI is bad?try 4800PSI

 

[patrickc]

The information that the tech at DPP gave me was for my 02 7.3 if that makes any difference.

What pump you been using for 4800?

 

[94f450sd]

the stealth.i hit 4800 when the gasket between the rear pump and the adapter blew.im sure it was higher than that as when i let off the throttle and looked at the scanner it said 4800PSI

What is Tony asking for? When I talked to Tony about tuning he didn't recommend the high numbers some are running. I've seen 4500psi spikes when upshifting but not sustained.


Didn't you know that the Stealth isn't capable of high pressures.
