You actually will not need to remap the dme, so long as you keep the maf housing the same. The dme cares not the displacement, it just needs accurate measurements of air coming in, so that it can deliver the proper amt of fuel and then have it check out on the exhaust size. If you change your maf housing, however, you will need a new map. PIWIS II is what you'll need - I wrote up a diy on flashing procedure a few years ago.

I don't think that the 6 speed bolts to the 2.7. Someone check me on that, but I'm pretty sure the patterns are different.
