Ahhh well slow and Victoria go hand in hand haha just kidden.....
Mate, JEM tuned for safety, they set the tune So I could thrash it, limiter bash it and it maintain safe AFR's..... I can run 21 psi safe on E85 but on 98 18 is the safe limit.... There is ways to set it up so it changes, but of your now clued up enough to change the boost controller, you shouldn't have a powerful car lol.....
