You don't turn the fuel pressure up...you adjust the fueling via the chip. If you have Erics 5.7 chip you can add/subtract 20 percent fuel. You can also adjust Julios alky kit...it's in the Alky Section. Here's a vid on how to adjust Erics chip from my channel.
I would just like to add, though it may not address the OPs specific lean numbers, but may be helpful to others, I had been chasing O2 numbers on the lean side at WOT for a long time. I was afraid to stay in it in high gear because scanmaster numbers seemed to be in the low 700s at 95 to 100 mph. First, I installed a DW 300 fuel pump. That didn't help. I got a Kenne-Bell boost a pump, set at and delivering 16 volts to the fuel pump past 3 lbs. of boost -- that didn't help. My next move was to change from my 50 lb injectors with fueling set, by the way, to the maximum value (154) to 80 pounders from TT with a corresponding chip to my engine upgrades, set once again to the maximum fueling (154) -- that didn't help. But. finally I found what I needed to correct the problem. I contacted Eric and had him re-program the chip for the next power level which added, I believe, about 20% more fuel at WOT and that was the key to fixing my lean at WOT problem. Hope this helps someone else.
