withamc, read the other fuel pressure thread to see my response to what you just said. Just for a little clarification hear, however, I will say my statement was referring to air/fuel ratio throughout the rpm range and not just at max HP. Your fix for running rich only effect air/fuel ratio at peak power.
How do you know that pete1 is running rich at WOT? Maybe his O2 sensors are working properly and yours aren't. His MAF meter may be calibrated differenlty. How do you know that his car doesn't run better rich at WOT? It varies from engine to engine.
