if the profile is incorrect then you will get incorrect speedo readings. So if the profile is too high then the speedo reading will read too high and the car will be going slower. For example sppedo reading reads 70 but you are in reality travelling at 65 mph. So the car will feel sluggish. If the profile is too low then the opossite effect applies and you run the risk of speeding. Eg sppedo says 70 but in fact you are travelling at 75mph.
