I've fitted de-catted header pipes, a Remus Hexacone muffler plus a Power Commander V, with the correct map, to my 2010 GSA . I honestly can't feel any difference - am I missing something? Others say it really opens up the mid-range and responsiveness, define for me 'responsiveness' and 'mid-range'. Please explain to me what or where the difference should be.
I'm not new to BMW's or bikes in general, I've currently got the GSA (my 7th BMW) a GTR1400 and a Harley Softail Custom
