If you are going to run anything other than the default it would be better to just upgrade to the jb4 and have the additional control inputs and integrated data logging capability. Without the logs you really don't know how you car is reacting to the added boost. One owners experience could be vastly different than yours based on the variations in the engine and regional fuel quality. There is some comfort in the fact that burger did a lot of testing with the default setting which is why it should be "safe" in most applications.
