I tuned my regulator to just where I could see the rail pressure start to rise at idle then backed it off. It stayed that way for about a year untill it failed. I hope this is the reason for my low rail pressure at WOT ive been having.
Im pretty sure I remembered sending in the warranty on my pump but I don't remember exactly when I got it, but I did e-mail them.
My truck ran fine with a 3200-2800us tune with all stock parts just the lift pump up untill a couple months ago it started to lose rail pressure at wot, which I thought it was my stock fpvr but fixed that and its still not working.
So I don't know if the regulator in the raptor will still supply the same pressure as it does at idle when the CP3 regulator is fully open?
