Hope they didn't charge you too much...one hour is not a dyno tune. I doubt that they did much beyond what you could have done yourself with some tweaking of the tables and a couple of seat of the pants test runs. An actual dyno tune takes 3-5 hours.

I just had a D&D Fatcat 2-into-1 exhaust, SERT and Arlen Ness Big Sucker installed on my 06 Dyna Street Bob. They did an hour dyno tune and here's my results.

Seems like the general consensus is that they gave either gave me a "quickie" dyno job or are super-quick miracle workers in dyno-ing (or maybe the Mustang has some super fast speed to it). I don't necessarily need the tuning file, I'm just curious what map they used on the race tuner (since I paid enough for it) and am concerned since most feel that a complete dyno should take 3-5 hours whereas mine was billed for 1 hour.

Most Mustang Dynamometers are eddie current style,very popular in the automotive chassis dyno business. I would guess that there are more eddie current Mustangbrand chassis dynos used there then any other brand. DynoJets usually read 10-15% higherHP/TQ numbers then the many other brands of dynos in the automotivedyno arena,I'm sure it's true in the motorcycle dyno arena also, it's better for business to read higher.
Tuners are not abligated to provide theircustom tuning file unless agreed to in advance, thensome maydecideif they will expose certain tuningtechniques to the public and their competition. There is a big descrepency in tuning skills from tuner to tuner because tuning is more of an art then a science and here again, likein the automotive tuning field,some of the best tuners consider their file a "trade secret" and proprietary. As the motorcyle tuning profession matures, we will probably see more of this by top tuners. These tuners are usuallyso busy with a long backlogthat they do not concern themselves with the few who will not go to them for a tune if they can't have a copy of the tuning file.

According to the printout it's a Mustang Dynamometer Test Report. Also lists a website for the company www.mustangdyne.com.
When I brought it in they said they usually take 1-2 hours to do the Dyno tune, but they'd only charge me an hour. Do you think they did a half-*** job? Now what do I do??
