no tuner needed? i called this company for info about the 2 into one exhaust. the builder/ dyno/ design/ owner/ guy informed me that on th 09,s the computer got more advanced, now for 2010 it is even further along with the new 02 sensers, meaning that the computer will now compensate for a stage one on its own. he said at high elevations u would prolly need a tuner still. he told me that they have tested their bike quite a bit and with the exhaust they designed(this is a main stream company) and a heavy breather,the bike doesnt need a tuner, the performance will not change a bit with or without the tuner,this is due to the new o2 sensors... he said the computer isnt as advanced as a car yet, but it will compensate mixtures enough for road riding
