Potential twin turbo build, looking for injection advise

I am currently in the same boat you are trying to decide. I just ordered a Procharger for my stock short block 5.9 and wanted to go fuel injected. I'm shooting for 600ish horse power with 10 lbs of boost. After hours and hour of reading and research I decided I need to go Holley HP MPI. The problem? Can't afford it right now, so... I'm converting my Holley 750 DP to blow thru until I can afford the Holley MPI maybe next year. I could afford the Fitch 1200 PA but after all the mixed reviews just decided to do the carb until I can afford the fuel injection I really want.

I'll be running water/meth injection. Shooting for 10.50s by this September at drag week.
