I have not kept up with the latest stuff available on HP Tuners. Tinytuner may have more options, though.

We've ran I think 23psi on a turbo 3400 using 3400 pcm and map a few years ago
. MAP isn't really crucial for boost since it's only used in case of MAF failure, just imperative that MAF is working perfectly, and well tuned.
