I turned my base fuel pressure up to 53.5 so that I can squeeze another 3 psi to get me up to 23psi or so. My next step will probably be 1000cc injectors. The bigger DSMs that are on E85 are running 1200 to 1600cc injectors.

Some shops have done tests switching from pump to E85 and when only changing the fuel to match the AFR they are seeing torque gains of about
30. That is without uping the timing that you can do with E85.

Yeah I'm going to have to call B.S. on this as well.

I'm running 13t's and my 680's are maxed out with the boost at 18psi and base FP set a 50 psi.
