Your stock turbo is rated for 25#'s boost, anything above that is beond what it should be seeing. Without a Boost regulator on the MAP line you will defuel at 20-22 anyway...setting a SES light. I have pushed stock turbos to 28-30 without them blowing up but there more or less just heating the air...

Yup....go much over 25 and #1 the air is so much hotter, and #2 it is so much more turbulant....that with a stock turbo you are getting no real gains out of the added pressure.... That is what they referr to as the "map range" of a turbo..just how much pressure it can run and still be efficient... more boost doesnt always mean more power... Basically you still have pressure...but no more, and sometimes less volume of air in that given amount of pressure...
