Ok so when I go to get an MSD distributor, I have to get the one with the TFI module and the built-in ignition module and remove my 6AL box? sh!tty... I thought the new distributors did for you what the TFI does on the OE distributors. No? Ok so then I guess my next question is, how would I keep the MSD box and still upgrade distributors?
