Nytro xtx super gearing

[snopro24]

What's everyone running for xtx gearing on a nytro MPI supercharger at sea level? I have stock gearing now and am installing 2" challenger track as most of my riding is off trail. Any help would be appreciated. Thanks!

I run 19/39 with 2" track. Had 180hp first but upgraded to 220hp last year.
