Hi , I have a 95 R33, with an exhaust system, intercooler and HKS high flow filter. I have a GREDDY Profec b boost controller that is being installed in 2 days, what is the safest highest boost i can run at, and also how low can the boost be turned down to? any help would be greatly appreciated

The boost cant be turned down any lower than what the actuator is set at which i believe is .5-6bar on the gtst

you will find, without using an airflow converter or Apexi Power FC, that upping the boost wont make much differnce in power. As more air = more fuel on stock ecu map

As has been said, you cant decrease the boost below the actuator spring rating, which is around 0.5 bar.....

Walbro and Fuel pressure regulator are generally more important when your running much higher boost than standard on a larger/hybrid turbo, they wont provide any performance increase more of a security thing IMHO.
