    I have stock 85 GN, installed one of your chips and fuel press reg. What are you thoughts on a boost controller, if you agree what do you think would be a safe boost pressure?

    Either an adjustable wastegate actuator or some type of boost controller would be good so you can fine tune the boost. In general max boost for the 84/85 cars is around 11-14psi on 93 octane before you start to see knock.
