Have DIY make sure they have the BIP373 installed on the board for firing a coil. (IIRC the 3.57 MS2 doesn't come with this it is considered a "mod"). Also, if it were me, I'd have them mod the board for electronic boost control and install the going low circuit for flat shift so you can wire a clutch switch into MS. I bought a 3.57 originally, then gravitated to a 3.0 I built so I could have more "usable" features. If they mod the board, and tell you what pins they terminated those signal wires to you have everything else covered it seems.
