asking the cummins forum technical questions about powerstrokes, thats funny. If they're saying 37psi on a stock turbo is normal, please don't take any more advice from them. Ford didn't change anything in the middle of the production year of 2000 other than the radiator and the rods. May not be what we're used to? A lot of people here have 2000's, ain't a special year or anything, it's what I have. You're saying it doesn't defuel at all.....at 25psi, when the check engine light comes on, it is defueling. Unless you have an overboost annihilator of some sort, its defueling. why would you waste money on a banks product? Cummins guys tell you to get that too?
