That’s actually a normal top speed for a Focus Ghia TDCI, but how long is the stretch of road? It would be a bigger accomplishment if you reach that speed in less time/distance than in stock. How fast did you get to 60MPH? Anything in less time than 10 seconds is a real accomplishment.

People don’t normally care about top speed as much as acceleration. You rarely reach top speed on the road, but you merge on the highway all the time.
