I have been reading all the post here on the EFI. I just purchased a 2010 TXC 250 which is in route from the distributer. I have not asked the dealer yet on any issues with the EFI. I thought I'd hit up the true experts on here first. I guess the first question is will this 2010 have the most recent flash and will it be effective? Second, power commander just finished their application with an optional auto tune. Are these worth the cost? Third, once you start with either the ibeat, and power commanders how sensitive are these bikes once there programed? I guess I am just hoping that I don't have to tweak this thing everytime I ride. But at the same point I don't want it to fall on it's face 20ft short of a take off so to speak. And finally will this thing come with restrictions? Spark arrester, throttle stop etc.. Give me some updates !! Thanks
