Any idea what this is? It looks like a boost controller, because there is a vacuum line off it straight to the wastegate... 2 other vac lines off of the unit itself, and a 2 wire plug as well... Anyone know how I could use this, or if I should even bother?

 

i have like 3-4 of those things...tried to use one once, didnt work (maybe jsut 1 psi?), but my buddy said it might not have been a good switch (giving a constat contact, just a momentary)....

 

Just like most Factory Boost controllers, they are for when the car is cold, it probably bumps the boost down to WG minium (8psi) and runs 10 when warm. Nothing special, I'd pitch the ****** in the garbage since its controlled by the ecu.

 

i pitched mine because a TurboXS SBC will own it anyday
