hm, I put these variables in:
TOR's - Stock
Stock paper filter
Drilled air box (Non-Freak/Nark)
42 Pilots
Stock needles
2 shims
All snorkles removed
Sea Level
I get: 128 mains.
How did you end up with 157.5???
Those TORs are a bear to dial in sometimes. There are a lot of different variations of them.
More info needed...
