After 2 weeks of battle and replacment of opti,maf, and ecm it runs damn good. I only took to 4 k @2psi and wow this sucker is going to fly. I need to put the inline pump in. Fuel pressure never droped with the 255 intank, but i bet it will at 6300rpm. No codes and never moved past 160. Im just so happy i figured out the crossfire problems. Now i am ready for the 5th tranny to blow. Thanks for all your guys help I can now sleep at night.

 

i would reccomend against an inline. the 255 intank should be good for close to 600. if you are worried, get/build a voltblaster.
