If this is the great Rody Roem, I have to say, its a pleasure talking to one of the best tuners out there. Thanks for visiting this thread.

Quick question...How does the RB V12 5 port, match up to the OS 12TZ 5 port, as far as performance? I dont mind paying the extra money to get the RB if I know for sure it'll beat an OS12TZ, or even my Mugen X12 engine.
