Thinking about getting a tuner and the Hypertech 43hp gain sure is attractive and the price too. Unfortunately it doesn't have the flexibility of the Predator or Superchips products. I may after the warranty expires go with a slight pulley reduction (3.2) and possibly a cat-back exhaust but that would be it. Has anyone had a comparable hp gain with the Predator or Superchips tuners? Anything close?
