You have to remember that the Gtech is only going to measure the horsepower coming from the rear wheels, not the horsepower being produced by your engine....
For a 5-speed, there will be about a 15% power loss going through your transmission\driveshft\rear end before you get the power to the ground...
221 hp is about right at the rear wheels...
Plus, while being pretty darn accurate, a gtech is not as accurate as a dyno...
A dynomometer is really the only "true" measure of your car's power...
