E-303 idles mean as hell I thought it was a mild cam.

I used to run a T-rex inline (until it went bad after a year and blew both HGs), with a hp 255 intank stock lines/rails and 42s and no FMU (junk like t-rex IMO). the last run on the dyno showed the car going lean at 5000 rpm with just the 42s intank etc. I had a feeling the car wasn't going to have enough fuel before hand, but I figured what the hell, hp255 is supposed to support 550. Oh well, I'm in the process of a -8an feed, to twin inline hp255s with a pickup and rail adapters, I might buy rails though too, and a -6an return.
