Funny Dyno Numbers

So I dynoed my car this morning and my numbers came up:

283.2 HP @ flywheel
227.2 HP @ wheels

279.2 TQ @ flywheel
240.1 TQ @ wheels

The only mod I had when I did it was the 4.10 gears. Am I wrong or are these numbers off? Most of the stock dynos that I see come up at LEAST 260 HP at the wheels.

Your input is appreciated!

Numbers do seem a bit low. I take this was an MD dyno? not a dynojet?

Were everyones numbers low or just yours?

You do know that the dyno broke when the porsche was on it.

Maybe something was already wacky.

I was scheduled for 5:00 so I never got to try it out.

Sounds fishy. What type of dyno?

This is a quote from the guy who runs the dyno "A 30% lost is quite normal on a MAHA dyno".

REALLY?? I didn't know. That sucks big time! I saw you were scheduled for 5. I was on for 9am because I had to cut out to go to Mirabel for a paintball match. So I didn't get a chance to see anyone else's numbers to compare. But thanks for the heads up!

P.S. I just found out it was a MAHA dyno, but I'm not quite sure what that means. :redface:
