The rated HP on ALL GT enignes went up due to the replacement of the aluminum intake manifold for the NEW plastic turbo intake manifold and a few changes to the way they calculate HP ratings now(change just took affect for all 06 car and trucks). If your GT Cruiser came stock with the plastic intake manifold, then you got a 230HP rated GT engine. If you have the metal intake, it would be rated at 220. My GT vert', pre Stage 1, with a metal intake dynoed at exactly 200 WHP (that's at the wheels) before I did a bunch of mods, but the car was not fully stock either. Most metal intake GT's dyno fully stock at about 175-180WHP.
