One thing you need to remember about dynoing your car is SRT-4's suck on the dyno. My car Dynoed 220 hp and 240 tq stock and my best at the 1/4 mile is 14.1!!
A friends car (both 04's) dynoed 205 (or some lower number) and he has run a 13.1.

Dynos don't mean jack to a SRT-4.

Once you get some more miles on your car things will loosen up a little.
