I already have a 2 Bar credit for my E40 ECM on my 05 GTO. How do I get a 3 Bar?

255 kpa is the hardcoded limit in the pcm ie 2.5 bar which is the max you can do, even with a custom operating system applied on gen 4 pcm's such as this.
You can use a 3 bar LS3 map sensor but the scale will be off so you will have to adjust the tune. I am currently running one on my GTO.
I want my boost gauge to go up to 21 psi.
