We have thousands of customers, only one person was ever denied warranty from GM (customer did not return the vehicle to stock tuning prior to visit). Ultimately GM lost the case and gave the customer a new engine (faulty cam phaser that was already on a warranty recall).
We have had over half a dozen DDs with superchargers on them, and never had an issue. We do however, maintain them very well, and make sure that we are not beating on them in subpar situations. We personally have never ran a vehicle to 200K, but with proper maintenance and supporting mods, it is obtainable.
