sorry to hear you think the Auto tune is a waste cos everybody else that has used it seems very happy I just wish I was oiver there reckon I would sort it if I could hear it running and take it to its limits cos that how I ride I do not show no mercy when I get on "the Mistress" I ride to the Rev Limmiter all The time, I just had a thought check the connections under the side infill cover behind the motor I once had an issue when I got a bit carried away with the hose there is a connection from the Crank Angle Sensor which the PCV connects to and I somehow managed to fill with water while washing the bike, it caused the rev limiter to cut in at variuos different rev areas from 3,000 to 5,000 rpm and drove me mad till I was feed up and started to revert to running with out the PCV and that is when I found the this stupid plug which is facing upwards and makes a neat little cup that water can not drain from.... have a look it might be part of your problem, cos as I said every body keeps telling me they are happy with my map in the PCV with the Auto Tune
