That really means nothing. The N20 gets close to 40mpg on the highway, the N55 gets close to 36mpg on the highway. But the N20 is running 18psi of boost while the N55 is running like 11. Im glad you are enjoying the N20, but your reasoning why its faster than the N55 is poor and totally unsubstantiated.
