I was looking into getting a bit more detail on the ECu unlock for a 2015 RR. I've seen a few posts but never saw any technical data that mentioned the actual performance chance. I was curious if you knew where to find or if you know where I can stumble across this. Also, if you happen to know if the RCK is the same thing as the HP power kit upgrade. I've seen some confusion when referencing both, with no real clarification. To my understanding, the RCK is just something to tune with as opposed to the HP power kit is an actual unlock to the ECU.
