I took my car to get my predator custom tunned on dyno.My new numbers are 447 rwhp and 471 tq SAE on a dynojet.I would strongly urge anyone with a smaller pulley to get the stock pulley tune on predator dynoed its worth the piece of mind .Anyone near the Tampa Bay area i would recomend seeing Tony at need 4 speed in Clearwater Fl. :beer:
