lift pump pressure

Ok, just installed new lift pump and 2 micron filter. Stock lift pressure was 4-5 psi at idle and would drop to 0-2 at WOT. With the new setup, 20 psi at idle dropping to 18-19 at WOT. Is this excessive pressure for the CP3 or is this just fine? Thanks

20 PSI is fine. You won't have any problems with that.

Justice4all, thanks for the reply. From everything I have read I didn't think there would be a problem, but it never hurts to get a second opinion. Thanks again.
