Not noticed any flat spots on mine, but will keep an eye out now you have mentioned it. Would have been up for a remap, but it adds about 30% to my insurance premium with my current insurer, so not really worth it. Also I am due in court for a speeding offence in June, which will either result in me picking up 6 points or a short term ban, so would prefer to await the outcome of that first. They did agree to add a sports exhaust and spacers without charge though, so have carte blanche to sort those out in the meantime.
I've been hit with 6 points in September last year - funnily enough on my way home from the yearly Wales trip (which I'm going back to this weekend )
