02 6.0 2500hd with boltons, a cam, and a nelson tune. just wondering what i should be running for fuel pressure. I think i may have an issue at wot from a dead stop with my fuel pressure dropping too low, if i get on it say mid throttle it actually seems to get up and go better than if i just put it on the floor. I have a stock pump and was thinking it may be time to buy that walbro pump I've been thinking of... i think i may buy a fuel pressure guage for inside the truck...
