Today, I decided to try to increase the boost on the GN (and pull timing via the Translator Gen 2). Shortening the wastegate rod and the RJC boost controller would not take me past 19 PSI. I even opened the exhaust cut-out, but that had no impact either. I did spin the boost controller the other way and it did lower the boost. I do not have ECM-controlled boost (no wastegate solenoid); it's all manually controlled. Any thoughts on what to check?
