The Accessport (not familiar with the JB4) allows you to go in and adjust the tables that make the motor run and affect how it runs. You can adjust fuel/air ratio, waste gate operation, timing, etc. The factory settings for these tables are set for maximum reliability and minimal fuel consumption. You can get good additional horsepower out of the motor by changing these settings with a tune.
