So for those of you that have a 16 limited that run low elevation mountains like us in Alaska I finally got mine dialed.

This is a 16 limited m8000 with a 162x3 stock gearing. I'll be gearing up to 21/49 soon.

Pulls 8100/8150 cool clutches and back shifts great.
Stock team 76g
Dalton white violet primary spring 95/255
Speedwerx 155/240 secondary spring
48° helix

This is on my 16 m600 limited 153x3 stock gearing

Pulls 8100
Stock team 66g weights ground down to 65's
Dalton white violet primary
Speedwerx 155/240 secondary
Supreme tool 44/42 helix

The stock clutching was terrible on these things from the factory but this seems to work well if anyone is looking for help.

you should try the 43 helix in the 800 works well for low elevation

I tried the 44/42 it just up shifted slower and felt lazy. The 48 works fine at lower elevation. I always run as much helix as I can that still gets me the backshift I want. I know people are running the 43 at higher elevation but that's just to make up for the lack of HP. Makes since that the 800 at elevation needs the same helix as a 600 at sea level
