Yep, Lagos is right.... auto trannys usually show lower numbers than the same car with a manual on the dyno... Heres a for instance.... Most manual 2.0L WRX's put down somewhere in the neighborhood of 285-300hp with my same mods. I put down 256 with an auto. Thats about 15-20% less than the manual. Sounds like you are right in line. The only car i've ever seen put down similar numbers as a manual are the GM LS1 auto cars. I had a 2001 WS6 auto, and i put down 298hp. Thats pretty much in the range of the manuals.

What "gear" did they dyno you in? That also makes a difference. In the end... what matters is trap speed and ET. Take it to the track to get a true sense of your power.
