mismatched non seqeuntial turbo?

Every once in a while I would get people that want to park next to the truck for miles going down the Interstate, which is unsafe in so many ways and also creates a traffic jam. I have been known to play with the throttle to get the turbos to whistle at point where it hurts their ears.
Sometimes I have to ride the brakes just a bit to induce more boost but usually about 5 seconds of it and they move on.
