I like the SDS because its compatible with almost anything. If you're N/A now and switch to a turbo, allyou do is change the Map sensor. You're probably better off going with the DIS option or run an MSD box. SDS is also nice b/c you don't need a laptop to program. You program from the compact programmer they provide. Also its a simple install. Take a look.
www.sdsefi.com I bought it cheaper from my engine builder, also an SDS dealer. I can help you if you're interested. Good Luck!
