What scaling do you use in the road dyno? i have an 08 wrx that i just changed to stage 2 ith a vf52 and did the dyno ith the scaling 9 and it read out like 333hp and 350something something torque...which I KNOW cant be right lol.

It's not a scaling as much as it's a smoothing factor. The higher the number the less smoothing is applied to the noise raw data.
You can change the value and re-plot to see the affect on the curve. The raw data is unaffected. Also note where the peaks are, sometimes if you abruptly lift off the throttle at the end of a pull it will show as a spike upwards and falsely show the peak HP there. In that case use the RPM limits to ignore the low & high end spikes.

Also, it's a tuning tool. You can use it regardless of the values reported to compare changes as you tune. It we effectively show whether you are getting better or worst performance with each change if you can replicate the environment conditions across each pull for comparison. It should be as accurate as the Airboy spreadsheet as the formula used is exactly the same. The only difference is how the smoothing of the raw data is performed.
