I need to run the car on JB4 map 1 with waste gate pressure only so I can provide some comparison data logs to my pro tuner. However the data logs between map 1 and 2 are almost identical. I have been running the car on 91 octane.

Any help would be greatly appreciated. Thanks
WG placement is trash on the doc race kits
