Hey guys, ive only had a 570ss until recently bout a 2014 exspess w a peak in it. I dont know much about it but i do know the rpm are low almost like there is something stopping it to be used at full throttle also the pressure regulator is stuck at 300 psi. Thanks in advance for all those that comment.

Any idea what rpm’s you are getting?

If the rpm’s are too low the pump won’t build full pressure either so that makes sense.

I’m walking out the door right now but I’ll respond later with possible causes.

Thank you Todd. I'm not sure what the rpms are at for sure. I just know that it's lower than it should be.

Put an electronic tachometer (Tiny tach or other) on it to see what rpm's it is running.
As far as the regulator? Stuck how? Rusted or corroded so you cannot turn the adjustment?
