Fuel Pressure with PFC

My fuel pressure is too high I think:

Idle = 33-34psi
0 Vac = 44 psi
10-11psi = 55 psi

I measured this with my Defi electric fuel pressure gauge.

Does anyone know what side effects this will have?

Thanks.

Factory specs are:

IDLE 28-32
0 VAC 38
BOOST 38 + boost pressure, thus 11PSI boost is 49

A litte rich but not not bad.

Yep, I get pretty much the same readings, and I have an Autometer fuel pressure gauge.

I got practically the same thing when my fuel system was totally stock.
