I think its the HPFP's inability to fuel the kind of tq this motor makes at 2k rpm. After that slight lull it catches it breath and is fine. I've had pretty good luck with E30 in my tank this go around. And now that I've gotten my issue taken care of I'll be rescheduling my dyno probably for this Friday. I also have to be in Denver in March so I'll see about hitting a dyno there to get some numbers off a Dynojet

I think its about a nickel cheaper/gal than 87e10 gas around here.

I wouldn't even think about it. I bet it takes Full-Race until the end of 2015 to have their full line of upgrades available. Not knocking them, just looking back on how long it's taken them to release everything they've announced on this site. I don't blame them. I'm sure the EcoBoost platform accounts for probably <5% of their revenue so they don't spend much time on it.

Our truck is now a twin turbo EFR, using twin top-mounted EFR6258 turbos, our new downpipe and intake. Fuel system mods are external FPR with a return line added, and upgraded intank pump (intank FPR deleted). Sadly our in-house tuning expert was recently killed in a tragic accident.
Friday-Saturday-Sunday we put the first 1000 miles on the freakoboost with the new twin turbo kit, for a track event in California. The single turbo kit development was halted, it will not be produced. Our website will be updated at SEMA time with details on the turbo kits. in the meantime the forum thread which gets most of the activity is here: https://www.f150forum.com/f70/defini...08585/index55/
there are a number of factors which delay progress on this platform - and GDI pump/injector limitations are the biggest issues right now. We are not putting this on the back burner. The 2 projects we are working on right now is this and our Mustang Ecoboost.
