A hub dyno will cost more than a roller dyno because the process takes longer (they need to remove all 4x wheels and connect to the hub dyno). A roller dyno (or rolling road) is a much quicker process and in my experience cost between $150-200 and the process will take about 30-40 minutes max.

Tarmac Engineering in Cleveland (not exactly close to Brendale, I know) not only have a roller dyno, but also do custom tuning for VW/Audi/Skoda. So they could certainly run the car on the dyno, and then he could retune the car to make it more like how you want it to be.

But I would certainly try speaking to APR first to see if they have a variation of the tune for your car that will give you the characteristics that you are looking for. Even if this costs you a small amount of money, its not going to be a total waste of money.
