Lol, I have well over 30 pulls on my last car alone because my buddy owned a DynoJet. I know a thing or two about dynamometers, but thanks anyways. I've done a lot of third-party testing, and most anyone that had a Mk3 Focus and was part of FF then transferred here can vouch for that.
DynoJets read higher due to being an inertia dyno as opposed to a load dyno, but not 30%+ higher. You should only see around a 12% (+/-) difference. That would put you somewhere in the ballpark of 210-215 hp and about 275 ft lbs. It's just ricer-math and doesn't really mean much anyways as you can pull different numbers simply by changing how hard your car is strapped down. It's only a tool for measuring delta-gains, which is exactly what you did.
You can't say that your torque reads one thing in one post and something different in another. If it's reading 390 then you are either looking at something different or you're getting a false spike. If it happens once, no biggie. If it's happening more than that you should update your AP3 because Cobb has issued updates to fix that. Considering the fact that your datalogs reflect what you see on the screen...or technically vice-versa...
Anyways, you seem to be the one trying to prove something so whatever-go ahead and do your thing.
