Airflow = 3000 lb/hr
Boost = 1.2 bar (120 kPa)

3000/2.2 = 1364 Kg/hr

Volume flow = [(1364)(.287)(293)]/98.1 = 1169 m3/hr or 1169/3600 = 0.32 m3/sec

Pratio = (101 + 120)/101 = 2.19

Plot that on the map below. You are in no man's land. No wonder your intake temps were so warm, only 60% compressor efficiency. You should go up one turbine housing size also (no map for that unfortunately). You need bigger injectors and a bigger turbo. Things are adding up fast! I hope you do it though. E85 is a great answer for a turbo motor. Watch out for the Bosch fuel pumps (if that is what you are using). I think some of them use a white plastic around the motor armature the disolves when exposed to alcohol over time.
