I sent my ECU to Steve a couple of weeks ago to get the Mountain Runner Premium flash. I sent it on a monday and received it back by that saturday, not bad for being 1000 miles away and there was very little riding time lost. All I can say is WOW what a difference. It's like I'm riding a completely different bike. So smooth that it's a joy to ride now, no more having to think about how I'm applying throttle and gear changes, it's now effortless and throttle response is fantastic. Thank you Steve!
