My buddy has a TD cat 2016 with there tune. set at 260 hp , we were in Canada riding my son was on the cat and I was on the sks, we were riding big trail in some huge fields and moving at 65 mph , I was ahead of him just cruising and we both hit it,and much to my surprise he could not get by me. I took it to about 90 and still was behind me at the same distance we started at. I was running the 1.5 cobra at the time too. and FYI my speedo reads slow,my son said the cat was at about 100.So needless to say I was happy about that and my son was shocked he couldent get by me.It was warm to 40-45 degs. and loose snow ,so that probably helped me with the track I had..
