The front clutches on the GT-R have a tendency to overheat when you do 30+ back to back pulls on a dyno. To preserve them most shops dyno tune the car this way once you start getting in the 700+ WHP range. Once the car is on the street or track this isn't an issue, but on the dyno it is just a safety measure.
