Because I like asking all of the "for dummies" questions:

So, if I don't have and added sensors or gages, I can get this for $599 and it just plugs into power and OBDII, no funky wiring required?

Was it showing a number for boost? Is that MAP?

Are the numbers it shows for AFR from OBDII or are those only if you have the ZT2?

What's a ZT2? (and how much is it?)
