Horsepower

It's a silly question but I'm asking anyways. I have a 2.55 upper a 10% under, arh long tubes, corsa 3", 7rt plugs, rotofab, 160 degree thermostat. If anyone has these or similar bolt on what kind of horsepower am I looking at? My car is on the dyno now and the numbers my tuner is telling me doesn't sound right. He's saying 560 at the wheels and over 600tq.
