I did 3 pulls on a dynojet in December just to get baseline numbers. Followed exactly what thread below said. I live in Hawaii so temp is about 85 degrees with 50-60% humidity at sea level. This is what I got

397 hp was the lowest pull. Highest was 405 hp. I think the coolest part was seeing my dyno specs overlayed on other customers cars. EVO's, STI's, Honda's, Supra's, Corvettes, 350Z, etc...

 

Interesting...I did 3 runs on a dynojet a couple weeks ago on my stock 2004. Low was 410 hp and high was 430 hp. My 410 hp run is posted here as the "before" dyno.

I put variables in for Hawaii weather conditions and they seem pretty accurate. I get a -3% for relative HP. So your 410 HP wth -3% comes out to be 397. High Temps and High Humidity steal HP. That's Hawaii!

 

Solid numbers, I know how humid Hawaii can be. That looks like it was at Hypersports.

 

It was at RAD MotorSport. Is Hypersports still around? I know a lot of them have been closing up shop...
