theres 2 versions
xcal and prp
xcal is 700 w/ map sensor from AGP, or 535+ buy your own sensor from Pwerks.
these are flashes the vendor send you. you cant see/adjust them.
prp is the full software. it is 1000 + the cost of the sensors.
the PRP isnt exactly tuner friendly, and makes the aem ems software look like a childrens book imo (easy). if you dont know how to tune a standalone or the concept, you are better off getting a flashed tune and be happy w/ it.
