If it's lean or a bit lean I would VERIFY with the mfg. that the fuel pump is capable of pumping enough fuel to prevent it going into a lean condition. Lean can melt pistons and rings....I would err on the side of rich vs lean.

Always happy to hear input and I enjoy troubleshooting problems like this.
The tuner set it up to run leaner at that range and I forget why. At any rate, the pump is making enough pressure to provide adequate fuel at WOT (7200 rpm)
I don't think this is a pump issue though I know guys that have run boost-a-pumps but they are usually making 1000+ hp and running FI above 15 psi.
