For one thing HP gains mean nothing without dyno tests to back them up. 20 hp from just an intake seems high to me. Secondly, a turbo upgrade requires larger injectors and ECU re-program. Sure he lists injectors before turbos but who would do the injectors without the turbos. I do not believe an aluminum flywheel increase hp. And 10 hp at that! No way. Show me the dyno. But what the heck. Stillen is as self serving as they come. He's in it for the almighty greenback. : Just got my copies of the new Stillen catalog and here's the new Stage chart according to them with approximate hp gain:
