Thanks wensum, I searched and read several times that the 27% is the most popular ratio. But until now, I haven't been able to find a post stating the 38% or 41% ran well up hills with a stock engine.

I'm going to make the modifications to the 38% and when I'm done, I'll let everyone know how it turns out.
