So just so everyone is aware, STD correction is about 4% higher than SAE. I find that SAE correction is what you want to use on naturally aspirated motors as atmospheric pressure and temperature effects are very well accounted for by the SAE correction factors especially if the dyno is done at different times. For turbocharged motors because pressure and temperature have a skewed effect due to the compressor staying between ambient pressure and temperature SAE and STD compensations start to deviate the higher you move away from 1.0 compensation factors (high altitudes etc).
