my tuner wouldn't print me one because he said he wasn't satisfied with the tune due to my "sh!t maf" I have to get SD and come back he wants to get over the "700 mark"

Why would he say you're over running the MAF? I have a very similar set up as yours now running the same boost and I'm not even close to over running the MAF.
 
I'll take it back after I get it painted. I'm still trying to figure out why it was going lean, I'm starting to wonder if my fuel pump was dropping pressure or if my maf was really being over run, I'm gonna get a in car fuel pressure gauge and make some pulls.
 
Bosch 044 inline and keep the paxton as a feeder pump to the bosch, or a single A1000. Might consider the new Walbro 450 as well, probably the least expensive option.

I'm running a fuel cell so I don't think that the walbro 450lph would work. I have been considering an A1000, but I just spent all my coin for the month on a Magnus smim.
