Fuel pressure at WOT?
So I just got done putting the updated fuel pressure regulator kit, Glowshift Elite fuel pressure gauge w/strictly diesel fuel pressure adapter, new batteries, and a new alternator. Also put in new fuel filters and a new SWAMPS 48V FICM.
Finished getting the gauge electrical hooked up today. Took it for a drive and at idle it is sitting at about 62-66 PSI. Even when I am cruising at 65mph it doesn't drop once I get to speed and am just cruising along.
Now the problem I see(which I think is a problem) is that at WOT with SRL tunes, my PSI drops down to 30PSI. Is this normal?? What are you guys seeing? It only stays down that low for a few seconds until it shifts then it goes up slowly as the truck gets up to speed. It almost seems as if it is starving for fuel at WOT. What would cause this?
From what I have read, a AirDog will solve this issue but with recent reviews, these things have been having lots of problems. I don't want to go through injectors due to lack of PSI either.
