2020+ YZ450F High Comp Map?

Does anyone have a base tune for the 2020+ yz450fs with a high comp piston on the yamaha power tuner app? I cant seem to find anything, only the one they have with the head work. Thanks

Make sure to link your bike first. If you haven't, switching maps right now doesn't change anything.

I have the PC high comp.. i said screw it and started testing maps..

Best one so far is the GYTR Head + Piston with u4.4 (mixed 50/50 works too).. I checked the plug after running it for 5 hours and plug looked great
