We create and test our maps for the perfect balance of engine logetivity & performance.  While we could make this map more aggressive, we want to ensure that it does not harm the engine.

Once you install our map, you can send us your logs from MHD or JB4 running the fuel of your choice & we will tweak the map for your particular situation.
