I understand where you are coming from. I also do all my own repairs and do not trust anyone else to touch my bike besides me. I was worried about having the ECU vandalized (so to speak) but know I didn’t have the tools to do it myself. After all the great reviews on this forum & no complaints (besides not having it done sooner) I took the chance and sent mine to Monster in Canada. I preferred that if anyone was going to do it that I would have the original person who designed it do it. Just made me feel a little more comfortable that way. In the end I’m 100% happy with my choice & no regrets. It’s a great mod for the price and the power & fun you’ll have with it will be left in the dust.
