Did you ever get this issue resolved? I'm a dealer, I've asked about a 12-rib upgrade on this setup and they claim it will not fit/work but now they have a 10-rib upgrade and I haven't gotten a straight answer if that would be a suitable upgrade either.

Thanks,

Nope. They offered a 12 rib at first but then when I called back to buy it...they didn't have it. So, I tried everything and sold it and went turbo when Procharger said the warranty would go away if I went cog.
