I might have my LX vert sold, and I am going to put the drivetrain into my 86 GT. Now I have a crane interceptor II, plugged into a stock EFI computer. IS a PMS something I need if I am using a C4? the guy who wants the car also wants the crane unit. Should I just take the computer, PMS, MAF meter and put it in the 86 which is Speed Density? Or should I sell the C4 and make the 86 a 5 speed car and no PMS? (the 86 is already a 5 speed car)
