Ulmer STM weight tuning

[burlyviper]

I have stock helix. I ended up keeping current setup for now (tungsten and 4 washers on tip). sled is up north and didn’t have time for any test and tune. Will re-access after the season is over.

i would stick close to his recommendation. Td tune I assume you want to be around 9000 rpm. I ran older powertrail at 9100. Precision tunes are all 9000 until you get to 3r and that’s 8800. Hurricane is 8800 on his tunes.
I run flat profile in cats too
I’m not a fan of stock profile
