Termignoni baffles ECU

[alibaba]

The Termignoni slip on system as shipped has baffles installed.  Upon removing the baffles it occurred to me that exhaust changes such as this require always required re-jetting on my old 'carbed' bikes.  Since the included Racing ECU is not programmable, what is it preset for  -  to run with or without baffles.

And if the latter, how do I adjust for no baffles?

Seems baffling to me.

I would think it would be able to compensate for just removing the baffles, although I may be wrong.

I just had Termignoni slip ons installed on my 1100, and the dealer left the baffles out.  I asked them if the bike needed to be reprogramed if the baffles were to be put in, and they said not.  They said a number of people take them in and out, like if they take their bike to a track, and there's no problem.  I think the ecu may adjust for air / fuel ratio.
