Tornado fuelsaver, Z-max, Timing Booster, Real or Gimmicks ???

There is no way the tornado gives you 12 hp! A good intake won't even get you that. And Zmax won't get you 10 either. That would be a VERY cheap and simple 22hp gain. Not practical. The zmax might help your car run better, but that's all. If you're spending money on one of the above, get a nice ignition, but only after you get I/H/E.
