First off, i am new here, thanks. actually have numerous questions. i have a friend that is building a 1970 Cuda. he is using a new '07 6.1 crate engine(5037400-ba) with a '09 RFE545 trans. he has purchased a bunch of new parts for me to install.(he is a body man, and i am a tech). soo i installed his FAST fuel and ignition modules but now come to find out there is no stand alone Tcm available. he also has an XV single plane intake installed which is a 4150 configuration, but we need to install a DBW throttle body and pedal assy. i am thinking the best would be to remove the FAST setup and just go to the chrysler ngc pcm and go from there. what would your best advice be? Thanks
