Yep 12.5 lbs of boost on my bone stock 5.3 ly5 for the last six months no problems but tune is spot on. TUNE TUNE TUNE is key and common sense if you wot everyday its not going to last forever. Im getting ready to cam mine with a pat g cam and add some meth. No belt slip yet with the 3.0 pulley

5.3
I have a 2006 avalanche Z71 LT with a 5.3 running 20lbs. of boost on a procharger set up. meth injection a cam long tubes and a weiend intake with custom wireing harness and throttle body. this was built by slowhawk in bridgewater ma. he did the build for me all the dyno work and custom tunning. im currently laying down 565RWHP and 460RWTRQ all on stock heads and bottom end. tranny and rear are built also but this awns the question about stock bottom end limitts and stock heads.the 5.3 can handel alot if the tune is right and the meth is a must if you want high boost levels. also went to 8 rib pullys do to belt slip at these levels.
