Message: [QUOTE="Charles, post: 1477834, member: 103"] I plan to up my VOP from mid 2000's to a B code VOP anyway. I have a sneaking suspicion that my idle haze might be in large part due to my extremely low VOP setting that was a carryover from an earlier time when fuel/time was my most important goal. Now that injector speed is a plenty, I'm interested in upping the VOP with a B code set and seeing my memory is accurate on what I found many years ago when doing so. Swapping P&B's is moot at that point. I don't need a gauge anyway.... it [i]is[/i] dropping pressure. As many fuel pumps as I've had fall down on me, insufficient filter flow rates and the like when running higher power setups on my other truck I can tell, it's laying down in the fuel delivery up top. The light missing after a long pull is another clear indicator. Not enough that anyone in the truck riding would likely notice, but anyone in tune with a 7.3 would notice it right off. Little bit ragged due to a bit of air getting in the rails on a pull. This has been going on for at least a couple years now, so it's not a current event in any case. Just figured I'd toss out the fact that aside from all the other stock engine systems, the stock pump seems to be a bit overwhelmed by the 3/2's even when tuned for a PMR. If time ever permits I'll dyno the thing. It's somewhere between 3 and 5, lol. [/QUOTE]
