LOL, for what its worth i run a dirty old HKS filter in my engine bay with no shielding just a duct to it I am going back to std airbox so I hope it isnt going to hurt power
Yeh, I am betting its the length of pipe before the manifold. Some people have problems with the 6boost having boost creep when they plumb the gate down near the steering rack rather than high up near the collector. Thats the reason I got rid of my Trust Type R gate as it was too large to package near the collector.
