This video may help you with installation of RockShox® MegNeg Air Can 2020 (MegNeg Upgrade Kit). Installation has been done on my CTM Scroll Pro with RockShox® Super DeLuxe RC3 205x65 Debonair Rear Shock, installed with 2 bands in MegNeg air can. Actually later I removed all bands from MegNeg and let the gnar dog token in positive air chamber. This setup works for me best at this moment.

Air Can Tuning Negative Volume:
Standard Air Can 100 %
MegNeg with 0 bands 211 %
MegNeg with 1 band 199 %
MegNeg with 2 bands 188 %
MegNeg with 3 bands 176 %
MegNeg with 4 bands 164 %
