I have had the NST crank pulley installed for over 3 months... zero issues. Never had the car dyno'd but at least 5-7 whp gain from the pulley alone. It's free horsepower. Doesn't hurt the engine in any way it simply frees up rotating mass. One of the cheapest safest ways to gain power on just about any vehicle and doesn't require a retune... the only time I could see a tune being needed for pullys are maybe belt driven supercharged engines, but not N\A or Turbo charged vehicles.
Performance Mods: Custom full exhaust (scuba removed), Injen Cold Air intake, NST Pulley, DC Sports Header, TB Performance traction bar & mid brace, GodSpeed Mono SS Coilolvers.
