I have a 93 mustang and I am thinking about swapping to speed density. My question is reguarding what wiring changes will I have to make and what parts do I need? Yes I know maf is better overall but I'm not making any cam changes so idle quality should not be an issue. My ECM went kaput and I'm having a hard time finding a c3w. But friends recommend the sd setup cuz it makes more power stock for stock.
