Tryed disconnecting the tps today. I did solve the high rpm shutdown i was having. Returned rev limit back to normal predictable opperation. As for any performance gain I couldnt really tell other than it is a gain when you know when the dam bike is going to hit the rev limit. Before it would shoud down at different rev's after 7000. And not just break up as normal but completely shut off for a few seconds. There must be a problem related to the tps or its settings. With it disconected I havent as yet noticed any adverse effects such as ping,etc.
