For only $100, I’d do it in a heart beat. A one time fee will give you not only the piece of mind of being able to keep an eye on your motor and how it’s running with the JB but also it enables you to choose your mapping, map 6 is what everyone preaches about on here due to being able to pull back on turbos after about 5k RPMS. I’d look at the JB4 forums on here and it will tell you everything you need to know but it’s only $100 for SOOO much more!
