Overview:

All data was logged using a DynoJet Dynamometer with the GTI operating in the fourth (4th) gear.

The ambient temperature in the garage during the logging session was 78 degF.

The SAE J1349 standard day is 77ºF and therefore the application of the SAE Correction Factor should cause minimal change to the recorded values versus the uncorrected readings.
