I dig that. For me, turning the screw out decreases the sensitivity of the accelerator pedal. It's almost like my TIG welder pedal. I can set it to max out at 75amps and give me a very precise feel for welding amperage, or I can set it to 200 and *very easily* burn through. Options are cool but I'm an old school hotrodder. I need an external "self control" device and this works for me. I did notice my boost goes to nearly 15psi at times of heavy acceleration. I am working on adjusting the LDA to give me a little more when I really need it.

If you have a question ask it.
I've done this repair.

The ball bearings are reused they seal themselves, pressed fit.
You see them in many places on the pump to seal up a passageway.
Soo no o-rings on the pivot shaft.

It might have broken in half and lodge itself in another location. If you could see a picture of it, that would confirm this. I'm betting the gentlemen from Michigami has one.

Did you poke around?
Sometimes a brittle old black seal can look like metal.

Is it possible to get the picture of this repair. When I first saw it they were there, now that I am ready to do the repair they are gone.
They were great pictures and very helpful. Thanks
