I was looking at upgrading my SD to Maf, (it's an 86 gt). As I was reading up on the swap, it looks like you really need to do the maf, wiring harness, and computer at the same time. Correct that if I'm wrong. My question is the computers...I've read that many people use the DA1, and I've heard a lot of people using the a9l. Any advice on what computer I should be trying to find. I'm looking at eventually doing a stroker 331 or 347, or doing a 351. The car is t5, and I'm looking at 400hp street car.
