I've got a PCV currently installed on my '07 M109 that's running a zero map. Rather than getting a custom tune I'm probably going to go with a flashed ECU. So, I'll either continue to run a zero map or, if anyone's interested in purchasing my PCV I'd be willing to remove it. I'm thinking $225 is a pretty fair deal. So, let me know if you're interested and I'll pull it off the bike.
