We are also working with PRP on these kits. We are buying a couple of early kits to run on our cars shortly. Retail we are told is under $1000. We will be using this kit, and our Adaptronic to take Spark duties away from the Factory DME so we have complete stand-alone control for the Sequential spark cut, 2-step, anti-lag, etc. Our Factory ECU is doing less, and less these days.
Why not just go Syvecs at this point? Your car wouldn't count for any stock ECU records now anyway.
