You CANNOT program anything or tweak anything to make the wastegate hold till a certain pressure level, because it simply doesn't know what pressure is present.
High IAT temps (I recall something about this)
Lean fuel condition
Fuel cutoff RPM is reached
High trans temp

22psi? With what? The magic super-duper amazing boost producer? You CANNOT make an M62 produce that much boost. BARELY half that. Even if you could, you would produce so much heat that you'd melt a piston and destroy your engine.
We're not busting on you here, but we need to make sure you understand this. I suspect someone is filling your noggin with fantasies and misinformation.
John Wikoff (above) and I are perhaps the two most knowledgable Series 1 L67 guru'* on this Forum.
If you want 22 psi of boost, go TURBO, with a bigass intercooler and a custom PCM. Beef up the entire bottom end and the transmission. When you're done spending that $15,000, we want video.
You need to quit talking about boost pressure and start thinking about how to increase FLOW through the top end, so you will see a DECREASE in boost pressure. That means you're actually using it and getting the best out of it.
Don't fall prey to the ricer-mentality of 'more boost!'. This isn't a Turbo 4-banger rice-bomb.
