Removed it from my 180SX Last night, and is in perfect working order.
Has on / off, hi / low boost, and an adjustable gain for wastegate response.
This really is a very simple boost controller to use, and one of, if not the most stable, stand alone units for controlling boost.
Will require some 4mm Vacume hose to plumb it in, but all the wiring harness is complete. Also includes the units mounting bracket, and if your local / willing to travel, Ill even fit it!!
