My APR stage 3 gave a dyno tested boost spike to 22psi, then settled down to about 20. Fell to 18 at redline. Likewise, other software I have tested with KO4's all consistently push 20 psi. And, yes, K03's on race feel feel close to K04's on 93. Still, you should be making more boost. Where are you reading your boost from?
