Thanks to Indy Evo!!! (Wilson D Fuel Rail)
Best Customer Service Ever!!!! 
Thanks Jim for Super Fast Shipping!
Not to mention a live text msg support
Top notch Quality! This is the biggest (inside diameter) fuel rail I ever seen for Evo
I'm going to install it today and Mark @ TurboTrix will retune me on race gas next week. I will post update when we hit the track next Sunday @ Import Face Off.
I just installed this too yesterday thanks for the tip Jim on how to get it beaded

Switching to Wilson Fuel Rail from stock rails made my Inj duty cycle jumped from 93% to 84% @30psi boost without touching anything in my AEM.

The idea is that a larger plenum volume helps to equalize the fuel pressure reaching each injector. If his IDCs went down, that likely means that the cylinders feed at the end of the fuel rail were not seeing as much fuel pressure as the cylinders closer to the fuel rail entrance. I suppose its also possible that the small inlet diameter of the stock rail may be been causing some turbulence in the rail or acting a flow restriction. However, I think the inlet diameter is the same as the diameter of the hardline that plugs into the rail.
