Just wondering if anyone has had any problems with running a ProCharger P-1-SC on the 4.8 @ 9 psi. I just replaced #7 piston (broken skirt). The guys at the shop told me that there must have been some kind of underlying problem and the SC just accelerated the failure. Any suggestions without a teardown to rebuild bottom end? I am also running Corsa exhaust, TR6 plugs, Taylor 10.4 wires, Flex-a-lite fans, powerstat, diablo. Thanks for any help you can provide.

 

I blew #7 on the 5.3. That appears to be the first cylinder to go lean. Good luck. Make sure your tune is dam good! Alittle ping can kill you engine very soon. Good luck

 

I did the same thing with a 4.8. I was running 15lbs of boost.

 

I always run mine just a little on the rich side especially with a stock block. How did you know the piston was toast?? To be honest Im surprised mine is still alive. Intercooler and meth, wideband and logging software is the only way to be safe. Throw one of those LS2 402 under there if you are going to do it!!
