My understanding is the mustang dyno is a brake dyno that applies a larger load on the rollers to simulate wind resistance as speed increases and emulates "real world" load on the car. A dynojet doesn't simulate wind resistance and will give higher readings than a mustang dyno. Either dyno is a good tuning tool although I think the general consensus is the mustang dyno is a little better for tuning due to the higher load applied. Either a dynojet or mustang will work well for tuning and measuring gains as long as you consistently use the same type of dyno.

I heard the exact opposite. I heard the Mustang reads higher and the Dynojet is the more accurate and desired of the two.

Mustang dynos will give lower results than a dynojet as they attempt to emulate real world driving conditions under load. Dynojets have no active power absortion device as a brake dyno does. The dynojet uses solely the weight of the drum as its load on the rear tires.

Mustang is definitly lower (usually ~5-8%), and it has a electric eddy-current brake that allows you to put a specified amount of load on a vehicle, which is very nice for tuning purposes. The Dynojet will give you bigger numbers though.

When the Dynojet and Mustang are calibrated to the manufacturer's specs, the Dynojet reads 10-20% higher then the Mustang, a non linear % depending upon HP range and drivetrain mods. However, many businesses either don't do it, don't know how or intentionally skew their readings to increase business which is why we have the above confusion. Example, I've asked many dyno operators if they are compensating for elevation and they don't know.
