dyno tunes aint cheap. but i would not want just a dyno tune, i would also want them to drive the car around and tune for driveablity. they will probably not tune out part throttle knock on a dyno.

but on the other hand dyno tunes are bad ass. they can run the car flat out in a safe enviorment and get the most out of performance, if they know what there doing. honestly, if they really know there tuning, they could get your car dialed in.
