Add to that it's a small roller Dynojet...and voila, you've got overinflated numbers

I thought the SAE correction factor compensates for all the temp/humidity/etc...

What are the correction factors on the dyno. Theres a nearby dyno by me that has a correction factor thats absurd. Anyone that dynos there gets big inflated numbers, make sure this isnt the case here.
The SAE numbers can be altered to produce higher numbers.

I was just at a 4 wheel dynojet... and we set the factor at SAE..... and apparently that is the closest setting to real life HP numbers... I didnt see any manipulation options...
just go to the track and run the car... if u trap 126 mph u have a 600 hp car, if u trap 123 mph u have a 550 hp car... if u trap 119 u have a 500 hp car... and if u trap 116/117 mph u have a stock car...

If your car is running lean you should be seeing normally more torque on the dyno not less, it was already mentioned above I believe.
The stock ECU will adjust for the intake and exhaust mods, you should not be running lean.
All of the above indicates to me that your tuner was not having a good day, or you maybe misunderstood what he told you.
In any case his dyno needs serious calibration/maintenance.
Don't get carried away by these anomalies, I would do my due diligence before using this dyno for further assessment of mods, it will obvoiusly mislead you.

That's the problem with most chassis dynos, very operator dependent, too many variables and corrections. With all do respect to Wross, there ain't no way in hell a stock turbo is putting down 474rwhp (maybe 374), we all know that. This just highlights the inaccuracies inherent in various tuner's chassis dynos.

Wait a minute!!!
Your saying you got "474 was best and 461 worst" with just an exhaust and intake.
then your saying "RUF 550 kit at 480 hp"
Erm, I would say there is definatlry something wrong there!!!

Or there is a problem with the altitude correction.
Bottom line - a stock ECU with an exhaust and V-Flow will not produce +540 hp at the flywheel.

don't forget he will have 1000 hp after the hybrid turbos are installed
