You guys remember when I claimed that the SPORT AUTO Supertest dyno measurements for the 991 Turbo S were incorrect? SPORT AUTO claimed that the test car had 607 hp. I claimed that, based on my information, they had used an incorrect correction factor and many here didn't believe me.

In the latest SPORT AUTO, they finally admit it.  Very interesting article about dyno testing in general (using a 991.1 Turbo S).
