Using the following setup I got the following results:
Puff Dino – 125
King Arms – 116
Airsplat – 110
Ultrair – 104
At 70C Propane (the only ingredient in puff dino) is 123 PSI. Butane is 25 psi, the others must add butane either to lower the cost or to lower the pressure to meet regulations.

Does duff dyno (sounds like a beer Homer Simpson would drink) also contain oil?
It would be interesting to check the standard Coleman propane as a baseline.
Yes, they all contain silicon oil. It is possible that accounts for some FPS reduction, maybe Duff doesn’t have as much.
