Said fk it, recently demodded the Regal and put most of the parts on my SSEi, perfect time to start running corn. Had maybe an 1/8 tank of 93 when I filled it up, so far have only changed the injector skew % from 100 to 120, no other changes. LTFT within 10%, no KR on stock pulley at 5 psi fully heat soaked with 3 passengers in the car (only hard mod left on her is the 3" catless dp), 11.8 commanded AFR. IDC is at 47%, still running stock injectors. Also stock timing table for the moment, going to start bumping that up soon to help make up some of the mpg loss, once I'm at 100% E85. $1.85 > $2.95. Gotta order some 60# injectors for the bonne so I can switch that to E85 as well.

Any need to mess with anything other than injector skew? Prefer not to mess with the IFR too much, if possible.
