oh you don't want that one. You need the spec 2, you should just give me that

No, There is a low boost and high boost if I remember then the other nob is for how fast the Actuator will open. If you set it to the low setting your turbo won't spool as quick cause it opens the wastegate parshally. For a quicker spool set it the other way....

had a profec b
great BUT
you need to change boost levels in gear!
strange but the controller will allow changes only while moving ( in gear)

strange but it does work well. i recommend using it w/ the high and low boost and keep in mind when the unit is OFF it will work at the wastegates' spring rate.... giving you 3 settings actually.

i have a spec2 now and no experience w/ it yet

"GReddy PRofec B

The GReddy PRofec B-spec. is one of the simplest, easy to use electronic boost controllers on the market today. Available in either Black or Clear Blue cases, the PRofec B-spec uses a reliable twin-solenoid valve control motor. There are two presets labeled Lo. and Hi., as well as a Balance knob to alter the wastegate boost response. This unit also can be used with both integral/actuator or external/poppet style wastegates good for twin and sequential turbo setups. Compatible with the GReddy Remote Switching System."
