btw, efi-diy, a while ago you said you were looking into the test code for gm pickup etc (should this be a plug directly into factory pickup, or have to replace the pickup?)

Also, have you had a chance to play with this yet? I am getting real excited about the prospects of this motor, not so much EMS. I think ms2 sounds very interesting, but want to make sure I am not cutting myself short by going with the "cheaper" solution.
