So with all the cars we dyno tune, customers frequently inquire about the different correction factors available to display the results. I have probably had a half dozen people ask in the last week and a half alone, so I wanted to post up some general information.

The industry standard for correcting dyno numbers to consider elevation, weather etc is SAE. This is also the correction factor you want to use if you want to compare numbers, different days, different mods, different dynos, car to car etc.

If you want to know exactly what your car made that day, that dyno, those weather conditions and your cars mechanical condition, you want to view the results in UNCORRECTED. These are the true numbers, but you will rarely see them displayed in this format. Reason being that many people like to chase dyno numbers, unless you are at a friendly elevation with optimal weather conditions, your not going to see those peek numbers as there is no correction in this format.

STD is the last one worth talking about. It is an older and inaccurate correction factor that yields higher results. Many shops and dyno queens use this format to inflate their numbers! The only time we will produce results in STD is at the owners request.

I hope this helps some...
