Power Performance Enterprises is at it again! This time they posted a video of an LB7 Duramax launching hard enough to break someones neck. Brandon Lee’s LB7 features a S483 single, 10mm pump, 60% Exergy’s, and PPEI tune. I honestly think this bad LB7 might sound better than one of my favorite sounding Duramax’s of all time. I’ll let you be the judge.
