It can be turned up a around 2psi 15lbft 15/20bhp and be safe and fuel save and still be with in the maf deviation limit map, exceed the maf diagnose limiter map and it will flag a light and limp mode.  But like Maxxeh said the best way would be have it mapped, this way you can get a kick of power down low and have more running added so the turbo ain't doing the work
