I have had the PCV on my 09 Street for a year and a few months..Did the cut down breather mod that was on here a couple monthe ago, love the look..The bike now has a decell pop..a little before but worse now..called FuelMoto, they sent me a new map. gonna do tomorrow, also sent me a map for my upcoming cam change, to the 255, the cams are in the cabinet (ebay find) just waiting for the warrany to expire, couple of months..Would love to go to the auto tune module just not in the budget right now. Any pointers for me out there? The map change will be a new experience for me, wish me luck....Scooter
