If you are confident in that, 155 mph is where your beast will top out, going down hill you may see 158 and that's all you get! Have fun an if you do it , remember your not the only one out there. Things happen , you see it all the time.(In know way, am I ,or any one else, on this forum saying ,it is OK to ever exceed the maximum posted speed limit set by your local law enforcement agency).
