Default Baffles and PV auto tune

My slip-ons are the stock gutted ones from American Custom. And I have their "mid-rumble" baffles for them. I usually do not have them installed, but last evening I put them in and ran some auto tunes with the PV.

Do the baffles affect the auto tune in any way? The wife prefers the bike without the baffles, she likes it loud. But sometimes I like it a bit quieter when out for a ride.

Just wondering if I need to get out and try a couple more runs with the baffles out.

When I had mine out everyone on these and other forums were telling me to put them back in.
Apparently the motor needs some backpressure to have low end torque.

I pulled the stock baffles out of 4 inch cvo mufflers and couldn't tell a difference in performance. Haven't tried autotune, but bet it won't make a difference. Now if you had performance cams from past experience it would affect performance a good bit.
