Holley blue installed

I got the holley blue installed today with my other pump. Fuel psi is crazy, its about 20-23 psi at idle but really jumps around. Whats the deal with that. Just the attitude monitor, or something else

did you run the holley blue inline with your stock lift pump? if so the stock lift pump can be working and not working which will really cause those spikes. if you have too much pressure at idle you want to install the pressure regulator that came with your fuel pump. I had the same problem when I did mine put regulator in and the pressure stays constant now but my lift pump only works now and then..
