Gated Boost Control Valves
Unleash the potential of your turbo with a Turbosmart gated boost controller. The "gated system" is unique to Turbosmart and will bring your turbo to full boost at lower RPM by reducing turbo lag. Increase the boost pressure on any turbo vehicle and yield considerable improvements in output.


Can anyone explain what exactly do the mean by Gated?

How would these compare to the XS Manual Boost controlers?

And how well would these work with the factory twins?

thanks for the replies... jc
