Pro Performance primary market is North America where ROAR approval is required. It's also a widely known fact that ZTW offers OEM services with some customisation such as FETs. Team Powers, Trinity, Reds, Zombie, Cayote etc use ZTW as the OEM. Read my post again, I never claimed Pro Performance have proven to use different FETs.
