The only time you even know you made a pulley change is while you're in boost. 90% of the time I am not seeing any boost so drivability remains the same. Unless of course, for some reason you decide to give it a little gas!
For the most part, it drives exactly the same, as long as you keep your foot out of it. The only problem I've had is when hitting a bump moving slowly in first causes my foot to involuntarily stab the gas. That's kinda bad
