Will a new map be required if a bike was tuned with a dB killer in the slip on and the dB killer has now been taken out?
I removed the dB killer yesterday and I did not feel a difference on the ride except how loud the exhaust is.
What do you wise folk think?

The slip on is an Arrow Thunder with a power commmander 3

Most of the time you would not feel the difference, it might make the slightest difference, but hardly worth the money. It does depend a bit on how well the bike was tuned in the first place, and how hard you ride it.
