The Zemulator will be about $400. The ConZult (do NOT hold me to this) will be about $300. That's a total of $700.
The idea of the Zemulator is that for $400, you can install the unit, download a safely tuned set of maps from my site that will allow you to boost up to 19psi (although not recommended, but it is mapped up to that point), set your boost to 16psi and have fun all day long. Its less than JWT's setup and further down the road it will allow you to finely tune your car when you have the ConZult.
