I installed this on
Subaru Impreza

Review
Fix this up together with my ABC. Very easy control interface and works well. You can use the pre-set timing to initiate the cool-down period of having the green light indicator of 30 seconds, red for 60 seconds and lastly orange for 3 minutes.

The STB works as preventive measure for premature turbo wear and failure. After a period of time letting the turbocharger work hard, it is important to let engine idle for a period, allowing the compressor assembly to cool in both the exhaust and intake tracts. I will off it when there isn't any boost done for 15 to 20 minutes prior to the ignition being shut off.

What I like
Easy control

What I do not like
nothing
