[SlowE92]

I live in Salt Lake City and the only gasoline we have here is 91 octane. I've had to buy 54 gallon drums of E85. I've seen mixed reviews of people saying to get a stage 2 LPFP and others saying that a stage 1 Fuel it will suffice. I want to run E50, would a stage 1 lpfp suffice? Also want to get a JB4 for Map 7, can I run map 7 on the stock lpfp? We have a 100 octane pump about 20 minutes from here. Thank you everyone.
