Something is fishy...

What were the SAE corrected numbers? The dyno posted are the actual #s. Comparing actual #s on two different days is not a very valid test, unless the weather was IDENTICAL (not very possible).

The correction factor on the Dyno Jet takes relative humidity, intake air temperature, and absolute pressure into consideration and what we've seen is the IAT sensor not reading correctly and throwing off the data. For that reason, we run in "uncorrected" to make sure you the people don't get misled. If we run SAE correction, the numbers are higher, but they still show an approximate gain of 35 rwhp. The temperature on run one was 75 degrees, barometer was 29.7, and humidity was 25%. The second run was 78 degrees, barometer was 29.7 and relative humidity was 30%. We consider this a very close comparison and no matter how you look at it, it picked up power. If we looked at the Dyno Jet correction factors we would have noticed IAT values greatly different between runs. All values seen above were taken from our weather station.

BTW: Here is a C6 graph I found on the Corvetteforum, look at his numbers...
pretty close to my stock numbers.
