Something is wrong with your dyno or the dyno scale. HP and torque should cross at 5252 RPM on every dyno
hp = (torque x rpm) / 5252
hp = (torque x rpm) / 5252

Do you think that I'm so stupid not to know which car I own? 250 or 350?
A guy which made dyno told me that 207.5 whp ~ 300hp. Dyno was made on the 4th gear with power mode off. I have also numbers from engine and it's about 250 hp where he said I need to add + 20% because of loss of automatic transmission while it was dynoed.
Anyway if it showed even 300hp from engine and as I know it must be at least 306hp thats I think I loose because of intake and exhaust. Even in perfomance I feel that my car runs worse than it was without intake and exhaust???
Dyno test was made on Superflow.

Even with a 20% loss factor for the auto tranny RWHP on the dyno should be ~ 250hp. Superflow might read low (I don't have any experience with it) but not that low. Or something is terribly wrong with your car.
Here's another member's baseline dyno with no modifications so you can see what a 'normal' one looks like.
You can roughly Divide .80 (to account for automatic transmission loss using your dyno guy's %) into the RWHP and it will give you the crank HP.
