I have been over 150 quite a few times with mine, pre and post tune. Usually done at 6:30- 7am on Sunday morning on the Turnpike (8 lane) on the way to the golf course. Smooth as you can possibly imagine. A bit noisy though. There is a nice stretch where you crest an overpass and can see a fseveral miles ahead. There usually is not any traffic at that time. I am very cautious. Done only when clear of traffic and dry. Tires are new and Z rated Bridgestones.
I think you could basically kiss your a%% goodbye if you hit something on the road or blew a tire.
But at least you'd be kissing it with the biggest smile of your life..!
