+1Yoshimura and Suzuki go hand in hand..
The suzuki race team uses Yosh, because they are sponsored by them.Every single bike is different. You're not going to get the full potential of any unless your get YOUR bike mapped,
so I guess to answer your original question, it doesn't matter which one you buy.
Yosh tends to fit best with Suzuki. That's why the race teams use them.
It really wouldn't matter to me which one, perhaps HPC would be able to tell you what they've been able
to squeeze out of a system. But, then again, they spend hours and a couple new tires getting it right.
