Welcome back to the Camaro 5 forums. Overall the ZL1 is a pretty solid vehicle to own. The only minor issues I have heard of was supercharger belt breaking, struts and shocks leaking,noisy differential,leaking rear differential pinion seal, and power steering failure is the only issues that I have seen. Also I high recommend keeping up on all your general maintenance like changing your differential fluid early,oil changes,doing all major services on time etc. If you are serious about installing a pulley and doing a tune. After you install the pulley definitely install a aftermarket heat exchanger and bigger radiator. Get a dyno tune from a reputable tuner after you install the pulley. Congratulations on the ZL1.
