I have a 1993 Ford Mustang with a 306 in it, with a Vortech supercharger on it. It was dyno tuned, so it still has the factory OBD1 ECU on it. The ECU has an SCT chip on it, and if I change anything on the car, I'll have to drive forever to have it tuned again, due to the fact that no one can tune OBD1. I'm looking for a user friendly system. I'm not apposed to changing the intake, injectors, etc., but I want my gauges to work. What would you all suggest? I would love to see what the car is doing!
