Hey I just put on a holley blue and I am reading about 25psi at idle. I've heard that 20 is the limit will this hurt my vp?

 

It's hard to say. If you aren't having hard starting, it's probably fine.

I'd say you don't need that much pressure though, and reducing it a little would be fine.

 

Just give it a little time, it may come down. At first my FASS was reading 22-23psi at idle and about a month or so afterwards its around 16-17 at idle or WOT, it never drops.

sometimes they just need some time to "break-in"

 

I'm running 27 idle for 2 years and no problems. You're fine don't worry.
