Fuel pressure too high?

I have a 80mm Vortech MAF body, stock MAF, 30# injectors and 8A001-026 (.562) sample tube. My engine is supercharged and has GT40p heads, explore intake, and 70mm tb.

I did a belt off (no boost) Wide band A/F ratio check with base fuel pressure at 42#. Cold startup A/F was 18-20. This went to 14.7 when the O2s warmed up. A/F was 14-15 though the RPMs with this setup.

I decided to raise the fuel pressure a few times. I am now at 66# A/F atcold startup idle is 16-18. A/F is 13-13.5 through the RPMs with some 14 spikes.

Is this amount of fuel pressure normal or is my MAF broken?

Just did a boosted run with a 4:1 FMU. Water injection set at 6psi and supplimented at 9psi. Durring this run I had a lean band of 19-20 A/F from 3940-4670RPM. AF was between 12.5-11.4 otherwise. No audible ping though since I had the timing turned back. This has me a little worried. Does this sound like a bad MAF?
