No I hadn't ever gone past 12psi because I had set it up to 12psi initially. Yesterday I went up to .94 bar though by putting duty up to 75 and changing the F/B to 5 instead of 3. I guess I can reach my set boost with a high enough duty. What I'm trying to understand is why I have to have such a high duty setting for just 1bar. From what I have read for one bar most ppl have a duty of around 50-60. But I have to be around 80 I'm assuming.
