New to the forum. Just bought a 2022 premium 3.0 in nocturnal. Not new to tuning as I have a 750 RWHP custom tuned 2020 Mustang GT with a whipple super charger. Looking at a JB4 unit and a custom MAP by 1fastsupra.com. Curious how you all deal with driving between states that have 91 octane and other states that have 93 octane? My custom whipple tune handles the octane changes. Do i need a seperate custom map from 1fastsupra for both octane levels? Or, do you get the MAP for the octane you use the most and then revert to the OEM tune when you go to a state with a different octane level. Thanks in advance for any info.
