Not bad!
Did they give you the WHP? (The important figure and the only one thats close to accurate for an auto)
Plenty of torque to go with it I assume?
It is worrying seeing your car on a dyno, but its only really the same as you driving along at 2500rpm in 3rd and then going to full throttle to the redline .. you do thatw ithout a 2nd thought, dont ya?
