No, SAE corrected will increase the numbers unless you're below sea level and somewhere really cold and dry.

Probably. SAE-corrected does take into account temperature and humidity to theoretically provide a standardized number. Given you dyno'd in the south and in the summer, it's likely that if it were SAE-corrected it would be a higher number.

Advertised 400 HP
How does GM get away with advertising the HP at 400 for the L99 and 426 for the LS3 when no one has dyno'd that? Did I miss something in the fine print?

These Dyno's calculate RWHP (rear wheel Horse power) Chevy calculates Horse Power at the crank.

Might as well post mine here.
First run is stock at about 700 miles. Second run is with rotofab cai and a tune done about two weeks later. |

Because despite what Top Gear tried to promote in their dyno test of a GT500, the number that is advertised is not the same as what you will be testing when you strap it down for a dyno run. GM and every single other automaker out there rates their engines with an engine dyno. This is a test rig that measures the output of the engine. A chassis dyno, which is what you most often see, measures the power at the wheels. This is the power at the crank minus any losses from the drivetrain.

You have to remember that there are Mustang Dyno's which add a load to the drums where the rear wheels are turning and the load is based on the weight and Co efficient drag of the car being tested. A dyno jet doesn't really have that kind of load and is calibrated differently. Just remember that not all dyno's are the same. Just use it to get your tuning down and take it to the TRACK!!
