Hey Im just wondering on what is needed to run a Th400 tranny and Multiport efi with the stock computer. Does the computer actually care what tranny is there as long as its set up for an automatic?? Does the th400 need a vss to show the computer a signal?? And if so where could I get one?? I have the capability to burn and program proms, Is there a way to set the program for the older style tranny. I will be using the 7730 computer and a holley mutiport efi manifold and rails. Sorry for all the q's and any help is appreciated. THanks
