High/Low (oil?) pressure shouldn't have anything to do with the fuel for HEUI Injectors. So, what mods do you have right now and what programmer/chip do you have?

Your stock injectors will take whatever fuel you can throw at them.... These trucks make 550ft-lbs bone stock. You have an hpop/tuning issue.

Correct.

thats why you shouldn't buy edge. It's calling for too much oil. So either your hpop is shot (very unlikely..) or you need better tuning that doesn't require the use of a boost fooler, as your "Edge" does.

All SD 7.3's need a boost fooler if tuned or they are leaving lots on the table.
All SD 7.3's when tuned will run out of HPO as the stock splits are very demanding and require more HPO than a stock 17* can produce.

I wouldn't bother trying to get the small amount (def. not 3qts!) out of the hpop...

Can some-do turn off the check engine code..maybe but its still running out of oil..same goes for a OBS..you can't tune out of this issue unless you limit the fuel being asked for which negates the reason you add larger inj's or get tunes .
