Nope, pretty flat, and more of an uphill than anything. It was pushed right up the the redline. It was really loud. The motor didn't sound enthusiastic about the endevor, but I was impressed that it was able to pull over 105mph. What impressed me more was that after I was flat out, and returned to 70mph cruise for the remaining 60 miles of my trip, I was still reading above 41. After this morning, its down to 40 even, but it warmed up for 30 seconds, and it is cold out. Oh ya' the antenna really screams in the wind.
