Oh no you didn't! LMAO!

Gimme a break on the accurate readings stuff. A Mustang, (or a dyno dynamics, or a dynapack) is only as accurate as the integrity of the dyno operator.

Dynojets give repeatable numbers from dyno to dyno, and the operator has no say in the final number.

The load bearing dyno's (Mustang, etc) strength lies in being able to put real world load on the car, and see actual real time torque gains at any given load point.
