Lots of old dyno charts for Nissan Skyline GT-R's. A dynamometer is a tool. Its like a ratchet or a multi-meter. In itself its just a thing. It allows you to tune and check a vehicle. People get so hung up in the numbers, the low reading, the high reading, etc. In the end a dyno is more safe than getting out and doing 4th gear pulls on the freeway, but some still insist on doing road tuning.
