Change the fuel pump. It probably is not doing a very good job keeping up with fuel demands at WOT. Especially since you are demading more from it now.

Re: Fuel pressure....

You can change the fuel pump inside of 3 hours easy. It is not hard to do at all. This is a good time to take out the rear stabalizing compressor as well, if you are not using it, which a set of Bilstein's will remedy just fine.

Re: Fuel pressure....

If you are still running the stock fuel pump, you should change it out with a pump upgrade. The reason for doing this is the stock pump was at the limit of it design pumping cap. From what I have found it's running at 85 to 90% of what it design to do with a stock engine. Changing the pump is cheap insurance for your engine. I'm running a Walbro 255 from http://www.raceprovenmotors.com/cart/index.php?cPath=44_74. I set my press at 45psi.
