Wow there cowboy. This dyno shows at the crank NOT the wheels. Yes our engines are underrated but so are the n54's. I like the NA more...to an extent. Our other parts are making me a little worried though. The tranny is different than the 130 as is our intake manifold. Our crank is different than than the 135. All these make me a little worried about the potential of our 128's. I want power gains but I also want the car to survive 200k miles as well. I mean at least untill I get my next car. I plan on keeping this baby as long as I can.
