Im actually doing a twin turbo project on my car (88 mustang lx) it has a 1979 efi converted 351w. Im using the stock computer, but getting an MSD timing retard box. What kind of information are you looking for? If you want a nice aftermarket ECU i would go with AEM. Its probably the best out there and you can tune your system with a lap top. Only thing is that it costs about 2000 bucks.
