I switched over last week. Just adjusted my global fuel setting to compensate, and my a/fs are alot more steady now. I haven't had time to really tune with it and play with my timing, but that will come soon. I fill up at Macewen on Bank & Catherine.
Make sure you have the fuel system to accommidate it, or you'll find yourself leaning out a much lower boost then your used to.
Here's some good info on E85 and injector choice:
Inj 100%DC 80%DC Global
720cc 40.24 lbs/min 32.20 lbs/min -18.75%
750cc 41.92 lbs/min 33.54 lbs/min -22.00%
780cc 43.60 lbs/min 34.88 lbs/min -25.00%
850cc 47.51 lbs/min 38.01 lbs/min -31.18%
880cc 49.19 lbs/min 39.35 lbs/min -33.52%
950cc 53.10 lbs/min 42.48 lbs/min -38.42%
1000cc 55.89 lbs/min 44.72 lbs/min -41.50%
1150cc 64.28 lbs/min 51.42 lbs/min -49.13%
1200cc 67.07 lbs/min 53.66 lbs/min -51.25%
1600cc 89.43 lbs/min 71.55 lbs/min -63.44%
1850cc 103.41 lbs/min 82.72 lbs/min
From that alone you can see, even with an evo3 16G you'd need at least 950s to max it out without reaching 100% duty cycles.
Note: Injectors smaller than 720cc are not recommended for E85.
