Customer brought his truck in for a supercharger install after getting it cammed by another shop. Look at what we found: broken bolts on the intake manifold, a missing cap on the fuel lobe, and the worst part—the AFM oil galleries are completely missing the plugs! 🤦‍♂️ This is exactly why you don't let just anyone cam these trucks. Quality work isn't cheap, and cheap work isn't quality. You get what you pay for when you try to save a few bucks! 🛑🛠️
