Dynojet Dynos do not give the most accurate whp/wtq readings.
Mustang Dyno's apply a load, via eletro-mechanical resistance, then rwhp is calculated based on how your acceleration per unit of time of this load occurs. Mustang Dyno's also factor in vehicle weight and wind resistance.
DynoJet Dynos simply use a large drum, of known mass, as its rotating resistance...Then rwhp is calculated based on how your acceleration per unit of time of the drum occurs.
DynoJets typically read about 10% higher, and are mainly used for "bragging rights" for horsepower. This reason, coupled with the fact that they are cheaper than Mustang Dynos, is why they have become the industry standard.
It's a shame that this is the case but it's what we have to deal with.
It really doesn't matter what type of dyno you use. What's more important is that you stick with one type or one specific dyno, to measure power increases.

no dyno gives you accurate real world whp numbers - the airflow is wrong, the load is wrong, etc, etc. On top of that you can calibrate any dyno to produce any number you like. What matters is repeatability. If you can do three runs on a dyno, and they all come back the same - that's a good dyno. Then you can do meaningful before/after comparisons, or tune for a good power/torque curve shape, so you know what your new mod is doing for you. Other than that dyno numbers are just for bragging rights

.I was stating that Mustang dynos are more accurate and useable. i.e. one example is being able to apply a specific resistance on their drums, which allows them to target individual loading cells at any given rpm in the ecu maps.

The dynojets can not be altered by the user so the direct comparison of car to car on a given dynojet dyno will be much more reliable than on a mustang where the user could alter some inputs to make one car appear more powerful.
The new dynoject 224xlc has the eddy current loading capability so you can now use dynojets to tune part throttle and drivability.
