I some how missed this thread! Very good information as well, having access to the dyno and be able to do minor things to the slants for better performance that doesnt cost much is great. Keep on testing for sure.

Hi
Great data, do you have a torque hp curve for a 225?
The ones posted here are not good enough quality to read.

thanks in advance
