We will have Power Commander V's ready to ship in 2 weeks. We are finalizing the mapping and seeing good gains on completely stock sleds with a 4 hp gain with no other changes.

Can put PCV on any 2006 and newer Apex as well, just a different part number than 2011!
Allen sent a email to you couple of days ago. Did you get it?
