I had the vac line going to my turbo come off and well the pic shows what happened
I had it set to 7PSI engine had 500 or so miles on it still breaking it in
lucky for me it was not tuned yet and did nothing but dump TONS of fuel and pull timing back
so far the engine 3000 miles later is still holding up just fine
I also run .75 bar for everyday driving till I get my 720s =)
Pissedofsol I thought the # 1 cause of blown engines was from the owners using delta wastegates
also if you guys are worried about over boosting you should install a pop off valve its on my list of things to do as with replacing all my vac hoses with steelbraided lines so it can't come off unless you take a wrench to it
