If you are going to dyno your car, you don't have to leave it on map 5. You can use a custom map6, or if you don't want to mess with that I would just run map 1.
I think it was peaking in the 14's in the CSV for some of the logs so wouldn't map 5 be better to dyno? I think i'm going to throw a 50/50 E85 mix in and do 2 pulls with E85 and 1 pull on Map 2 since that's what FBO cars should run, right?
