Its not about whether they are TOR mufflers. The greater flow in your 06 mufflers is because they will not have CATs inside them, whereas the stock mufflers do have CATs.
Triumph only have one map available for mufflers without CATs and that is the TORs map. That is why all mufflers (other than stock) require the TORs map.
Cheers, Richard
