Thanks 1slow, It just seemed like a big drop in pressure to me. But I am coming from the diesel world where if you lose 30% of your fuel pressure its just not going to perform like it should.

Thanks for the link Jordo!
Do you have a fuel regulator and return system, you not suppose to loose that amount of pressure, your pressure should be solid, I have a boosted car and had a lot of problems with pressure and I fix by getting a walbro 485 and 10G wire, I deleted VVEL and set a pressure to a solid 53, tuned and car got a solid 53 even close to 7500rpm.
