Buy the stud kit from Larry B. It’s the only way to go when fighting the tougher spring on install.

What does the pressure look like when doing a wide open run ?

I ran an eBay 140 gph on a relay feeding a stock lift pumps for a few years, than I got a new pump from the Cummins dealer and swapped a comp cam #375 spring iirc and left the screen out of the pump. I didn’t notice much of a difference until I removed the pusher pump. With the comp cam spring the pusher became a restriction. My precision industries billet input lasted less than a week after I removed the pusher. My fuel pressure can still get pulled down but it takes a little longer. Throttle response seemed better also.

I hit 10.91 with a racked 160hp pump fed by an electric pump @ 60-70psi. Hp was mid 700s.

Did you use a larger fuel line from the tank ?

FWIW, I just changed over from 3/8” lines to a 5/8” suction from sump, ported fittings, 1/2” dual feed and saw nearly 10psi gain at all RPM. Stock piston pump.

What did your truck weigh? And what did you figure you were at when you ran 10.91?

I was going to as well, was really looking forward to trying it. Just got tired of waiting since they've been on backorder so long, so i went a different route. Hopefully they are available soon and we can see how they work.
