How do I properly dyno test various maps?
This process is a bit more time consuming due to the nature of testing a normally aspirated (NA) vehicle. Dyno testing with 2-3 WOT pulls will not be sufficient for recording the power output of a stock or performance map. Our experience has shown that these and other NA vehicles need be be tested several times in a row, usually 3-4 on a Dynopack hub dyno and 5-8 on a Mustang chassis dyno, in order to perform consistently. This is necessary in order to bring the coolant (engine coolant temperature or ECT), engine oil, transmission oil, and combustion chambers to the appropriate temperatures for consistent results. You can see the results from dyno testing are consistent when you overlay two power curves and they are within 1 HP & TQ of each other across the entire RPM range. An engine will usually make less power on the first few runs after a reflash (unless the intake manifold (or ambient air) is super cold or cools down very quickly), and less power after heat soak has set in.
