yeh most of them lift the heads off when they try to push the stage 3 bully dog or hypertech, one guy who was a tuner put head studs in it and couldnt crap anymore than 50lbs of boost into it without lifting the heads. about 35PSI is safe... on the 6.0L anymore and that torque to yield bolts lift. also the VGT are having spider veins wear out and leak down on them and causing the turbos to burn up in them stock, and its also causing problems with dumping oil into the inter cooler. we had one at work get away from us. had it it park shut it off and it kept running. it went WOT with not regulation on RPM or boost for about 2 min till it burned all the oil that had built up in the cooler. and the only thing it did was tap a couple valves. so the whole engine was replaced under warranty for turbo failure... the new 6.0L if ur not careful will just plain fly appart.
