Looking for recommendations on the right carb CFM for a S550 Mustang. On the way home from work it lit up with “Advance Trac Service”, “driver modes disabled”, ABS light, airbag light and showed a wrench light at the same time as losing most of its power (this has since gone away). After spending $250 on the fancy autozone code reader which didn’t recognize an S550, I figure it’s time for a carb conversion. Whatdayathink?
