Car missing while on Dyno?

Hi,

A local tuning shop had a car cruise last weekend and they were offering dyno sessions/runs for $50.

I decided to put my 69 350 Camaro on their Dyno (Mustang Dyno) to see what was my output at the rear wheels.

To my big surprise and disappointment, my car started to in the mid - 4K RPMs. The Dyno curves (HP & Torque) shows starting to go down around 4,000 RPM while the curves would be expected to be still climbing until it start reaching the 5,000 RPMs.

While speaking with other friends of mine that went the shop earlier that same day, they told me that most of the cars that they saw on the Dyno were also missing at high RPM.

The questions I have are:

1) What would cause my car to be missing on the Dyno.

2) Will my car be missing on all Dynos.

Thanks,
Daniel.
