SAE correction factor is most common, standard correction factor will give you a tad higher readings (about 3% on the average, I believe), and uncorrected will generally give you higher readings that that. If you do a search under SAE correction factoring on this forum, you will find some very good info from some very knowledgeable people.
Correction factoring won't be as important for tuning as it would be for dyno #'s.
