I don't see a reason why you wouldn't.Yeah, I'm thinking of bumping boost to 26psi, just to keep the EGTs even lower!
Can you elaborate on this? I would expect if boost dropped off the pin would follow suit, providing appropriate fueling for the boost level, as the pin is boost referenced rather than RPM. What am I missing?Just be aware of the boost dropping off at higher rpms that will bring the compensator pin up and increase your fueling and EGTs.
The compensator pin should ideally be set to give a slightly rich spool (18-19:1 AFR) to increase the drive energy delivered to the turbo. This extra drive energy helps the turbo to spin faster, which in turn builds boost. As the boost level approaches your desired level, the pin either stops moving down due to spacers installed to restrict its depth or the ramp rate on the compensator pin where the pin follower is referencing either decreases or flattens. This is when your fueling level/stroke holds steady while the last few psi of boost is used to increase your AFRs and hence lower your EGTs.Can you elaborate on this?

A clever man like you should be able to nut it out gergWow man. This pin sounds like a PIA. Anyone ever thought about the possibility of removing this thingy......? I much prefer to control fuel the old fation way, with my foot.
My two cents is it sounds like the mercedes spring might have been too soft, giving you max fuel at mid boost level and hitting fuel cutoff when you were trying to get to higher boost/RPMs. (Again, I've only been playing with these things for a few weeks so I might be way off)Hmm, I wonder if the fuel pump would be twitchy and hard to control? When I put the Mercedes spring into my 3b pump many guys recomended it and said it was a large improvement, but it made my truck extremely hard to drive. 1/4 inch of pedal movment and the pump would go to WOT for a few hundred rpm then mostly cut out. I couldn't wait to put the 35 yr old spring back in. Might just be my experience, but a drivable pump is a lot nicer than a pump that just puts out the most fuel. No doubt the other spring increased fuel, but at a huge expense.
