You're really not more than stock, me either. Stock heads flowing through stock manifolds just don't breath that great. About 20% drivetrain loss with the wheel dyno. 240 hp is roughly 300 at the crank. I don't know what your engine was rated by the factory but you're getting most of it to the ground. My truck would probably put down better numbers with the stock cam than this turbo cam I'm running plus my dual springs are probably eating up some HP, too.
