I'm running V&H straightshots, ness air cleaner, and a fuelpak. I originally set the fuelpak for straightshots with no baffles, and forgot to remove the standard baffles because it sounded good. So I ran it this way for a good while, and as an experiment I input the settings for standard baffles yesterday. It smells a little richer now, sounds a little deeper, and I didn't feel any performance change. I did however notice a little change in throttle response. It seems like I have to twist a little more at first, but once I get moving it's business as usual .
I like the sound, the fact that it smells a little richer (might run cooler), and the idea that I'm running the proper settings, but I liked the quicker response with the other settings.

I'm wondering if any of you have messed with these settings at all, and what results you've had. Also, if I go back to the settings for no baffles would I be running too lean? AND, I may be wrong, but shouldn't the settings for no baffle be a richer mixture and the standard baffle a little leaner?
