Yea.... The AEM kit is just the right package for how I'm going to use water/meth. You're right, a Labonte or Aquamist would be a waste of money as I wouldn't use or need any of the many many features. My main reasoning for water/meth is just to get the cooler AIT and slightly higher effective octane to fight off summer heat power loss. Like the guy at Renn-spec showed with his E46 M3....there are major gains to be had without touching the DME and just tuning the water/meth to the car...safe and effective
here is a link for the kit
