Hey there, so it looks like i'm selling my PCv because DynoTech doesnt have a map for the 18' 800 Rush (they claim the factory mapping is great). I'll sell it for $350 plus shipping and like i mentioned it has the map from DynoTech on it for the 15' 800 rush pro-s. i still have the box and all install instructions, paperwork, cables, etc... Let me know if your interested, i'd just need to figure out the payment part.
