It works!

The item itself works great as expected. Shipping always comes quick. I've used ZZPerformance for several purchases on my custom builds. My only complaint is their customer service leaves a lot to be desired. Response times may be quick, but the level of competence and respect aren't acceptable. I'd have a hard time ordering from them again after the last few interactions. They literally sent me a used product that they tried cleaning up and passing off as new.

High quality actuator

This is a great, high-quality actuator. It lacks the bracket for the boost solenoid on the 2004-2005 GP. However, it costs a fraction of the price than the actuator with the bracket, and worst case you can just ziptie the solenoid to something and it works just fine. Overall, I’d recommend this to someone needing a new m90 SC valve actuator that doesn’t cost a fortune.
