-

Consult your local specialist before setting your desired boost pressure, setting boost beyond your engines capability may
result in engine damage.

-

Allow for adequate cool airflow around the top diaphragm housing

RECOMMENDATIONS 
-

Turbosmart recommends that boost pressure is set using a Dynamometer and not on public roads.

-

Turbosmart recommends that a boost gauge be permanently fitted to the vehicle.

-
