First time to have the Mustang dyno'd. mods are C&L cold air intake, Steeda Underdrive Pulley's, & Pypes offroad H/pipe helped make close to 300 hp at the wheels. other mods are a Hurst short throw shifter and Flowmaster American Thunder mufflers.
the dyno was performed on a dynojet mobile dyno. I would like to hear some opinions about the reliability on the dyno numbers from the dynojet.

Well, with your mods... about 300ho is a good number if you are running a 93 Octane tune. Thats roughly a 30hp over stock increase to the wheels.

What model DJ? If the numbers are SAE-corrected, they're fine.

I never asked about the model of dyno jet. but, I had been figuring the car would put down close to 300 at the wheels. just didn't know how accurate these dynos are.

If it's an older DJ, then it is likely an unloaded dyno so it's numbers are going to be higher (by about 10%) than say a Mustang Chassis Dyno or a Superflow.
