This is the first time I had a car tuned on a Super Flow dyno. See above post. I have used Dynojet mostly and my Tahoe once on a Dyno Dynamics. The Dyno Dynamics does read low compared to the others going by first hand experience. I did find this post from someone in the dyno business and found it interesting and probably close to the truth. As is often said a dyno is just a tool. The better it is in repeatability pull after pull the better you can see how the changes you are making in the pull affect the power output.

"The industry leader in number output by far is Dynojet. Their marketing in the mid-90's specifically used the larger output numbers as a selling item.
Next is Mustang, generally about 7% less than Dynojet numbers.
Superflow is about 3% less than Mustang.
Dyna-Pak and Dyno Dynamics are about 3% less than Superflow.
Ok lets make this point again to make sure it's clear. The SAME CAR on the DIFFERENT DYNOS. So our test vehicle output on the various dynos are as follows:

Dyno Dynamics 200hp
Superflow 206hp
Mustang 214hp
Dynojet 226hp"
