Then again maybe I am wrong, I only tune cars for a living and have set the boost on a 500+ of them by now... He was having a boost control issue, aka his wastegate wasn't flowing, aka he needed to address it with the ability to flow more air. If you give the compressor wheel a running start (aka more boost down low/allowing the wastegate to remain closed longer) why WOULDN'T it go higher? Again, Justin, I understand what you are saying, but his car was going higher on its own will, its a pretty common problem actually, something I get to deal with on 1/2 the dsms I work with. Unless we have a proper wastegate on it (or a good boost leak) the car will build 20+psi by redline easily, yes it will hold, but that overall boost spike will continue to rise until you run out of efficiency.
I really doubt we would tell a customer to keep the boost down for shits and giggles...
