thanks

I would....there is usually just a 1-3% difference between dynoes so there is something else going on. I've heard the dynapac's are stingy, but your hp #'s are similar to what early 2.7L engines put out, not even close to 03 S power. The huge drop in the middle of your torque curve is very strange as well. The TQ curve should be nearly flat.
