The 670whp and 645 wtrq was my car and I i gaurantee the Dyno wasn't altered I have probably 100 Dyno pulls just on my M6. My M5 stock did 545 whp with charcial filter. To bring some light to the so called Dyno operator theory, there's no reason to mess with the Dyno when I'm trying to prove before and after gains to bring true light to the upgrades including your favorite 60-130 Vbox runs.
Also we've dynoed other cars in the same Dyno with same results and different cars for example my cousins SL65 and made 524whp with exhaust upgrade. Then even brought a sl63 for pre Dyno runs before header and exhaust install and the car did 405whp.
So if your car didn't Dyno 670whp then don't put your two cents in. I speak from experience and don't appreciate calling my a lier. My car has world record 10.7 129mph. Those are the facts no reason to lie.
