I got a reply from Kito Auto Sport, and it sounds like they will take care of the problem for free! They will put in the STI restrictor pill and get the boost down to the levels I am looking for.

I also have a question on where the AFR should be. I am not sure what is considered to lean or too rich. It seems like AFR dips down too much when boost hits is 10.3 way too rich? Also, should AFR be a bit more rich as the revs rise? Would AFR above 12 cause really high exhaust temps?

If this is getting a bit off topic I can go to the tunning forum, just let me know.
