Steve, thank you for answering my question. But for instance, in your tune for Versys 1000, I think you make a bit different maps for stock exhausts and open exhausts, no? I am asking, because I have also send for the flash the 1000 ECU. For instance, you have for Concours something called Area P full system, for fully open exhaust, so there must be some difference.Why would you mess up the flash's hard worked fueling with a booster plug? I don't want any booster plugs, power commanders, dobek boxes or witches spells stepping on my flash.
And there's virtually NO difference because of the cat. Go look at my versys 1000 dyno charts. todays oen exhausts are not limited by the cats. They are actually very will designed systems, but the restriction is in using smaller pipe diameters that control power at a pre-determined power level.
