Pretty sure Steve is running a dual 255 setup. Otherwise I've been reading up a lot on the Bosch 044 pumps since I know eventually I'm going to need more fuel if I go with E85 and step up to a larger turbo. If I ever reach the limit of my pump, that's what I'll be upgrading to more then likely.
Also have you considered using a Bosch inline in conjunction with you 255? I've heard of people having success with that setup as well.
I will personally be going with the 044 though once I max out my 255.
Here's a little vfaq too. I got it off DSMTalk, and I haven't really gone through it yet, so not sure how good it is written.
