Dave,
How much will I give up on my YS 1.10 if I run 15% nitro instead of 25%?
I'm curious in the interest of $economy$.
Thanks!

Not much, but you will lose a lot of good idle and transition characteristics.

Dave,
As always thanks for you recommendations.
If I want to email you off line should I use the Performance Specialties address?
Thanks again!
JLK

Yep!
