Hey all, as far as i can tell, a good amount of people are running map 3 on their jb4s with minimal mods. At the moment i have ark secondary DP, and mbrp cat back. Ill be ordering my jb4 and intakes too. In canada i can only get ultra 94 octane pump gas, but i can easily add an octane booster. Which map do you guys think i can run safely without running in to problems due to mods/fueling issues? Thanks in advance!

. Better off using Shell 91. You will see it in your logs once you’re set up. What part of the country you in? Oh and welcome to the forum. Great place for everything Stinger. Cheers
