I would get a SAFC in additon to the maft setup. You'll be able to do get a MUCH better tune when you use both together. It's very difficult to get a good tune with just the maft, so nearly all the dsm's owners I tune for opt for the safc to piggyback with the maft. You're gonna need a stall+ with new valvebody to get get the most out of that tranny. AT.dsm.org will have more of the info you're looking for. There are some people that have had a lot of success with modifying the automatic dsm tranny, so check it out.
