ive done a little more research on some american sights, mine made consistently around 240-250, with headers, exactly what those in the states make, so for a comparison the figures should be accurate.
Stock injectors are good for around 520hp at the crank, tests done with a supercharger and totally stock everything including ecu gave around 280rwhp at 3-4psi, with headers a little over 300, at 5-6 psi with a ecu, fmic and headers 350-400rwhp....
Thats a stupidly impressive result, i think im gonna have to save a little faster
