Is 47 For Fuel Pressure to high

[red82gt]

No disrespect, jimberg, Adaptive strategy is fine and all but how does your car know its making peak power in open loop? The oxygen sensors are not used during open loop therefore your computer would not be able to precisely find the right a/f ratio, it only controls the pulse width and the computer has no way of knowing if it is supplying a rich mixture (especially with bigger injectors), the only way to lean it out is to drop fuel pressure.
I've seen cases where the same car ran the same et/mph time after time, month after month, only to pick up .2sec/1.7mph by dropping the fuel pressure from stock to 32psi, only to go back to where it was before after going back to the stock fuel pressure. It works!

I'm not chiming in on this one anymore, I know I'm right, and its been proven too many times in practice for me to believe what was interpreted from a book.
