These are two completely useless dyno graphs. What happens below 3400 RPM is relevant as well...

Newbie dyno operator? Take it somewhere that knows how to properly set up a car (including fanning it and dyno calibration) and do a complete pull, then you'll have a dyno chart that has any relevance. This is garbage.
Oh, and the crap about the Mustang being the "best dyno in the world...". Uh, no. Maha, DD, Mustang... they all have their place and provide different results. Mustangs are absolutely not the benchmark though.
