BMP Stage 0 stock performance tune

[M8 Cat Attack]

Anyone else out there running BMP’s torque link stock performance tune on a 22 matryx RMK 850 with there Y-pipe and head? If so what’s your thoughts on it. I have the same lean spot as the stock map and honestly don’t think there’s any gain. Going to put stock map back in again to confirm.

FWIW I have the silber flash on my 850 n/a. I really noticed a difference. Runs much crisper from the bottom and feels like the mid & top end are stronger. No flat feeling in the powerband.

Rode at Rabbit Ears this past week for the first time with the flash. 9k-11ft.

Will be riding at the Sled Den in March which is 4k feet.
