Well best of luck trying to find one... I was just at the Dinan site (
www.dinanbmw.com) and found nothing about it in their search engine or in their product lineup.
It's probably alot more expensive than the JWT...but I cannot see how it could be far better. Let me know when you get some concrete evidence of its existence and the HP it produces...the price would be nice to know as well.
Good luck...
