I've got this EVC II.

The Boost sensor (no pill) on it is hooked up to the same line as the blow off valve / pressure sensor.

The other two lines, one from turbo housing is hooked up directly to the solenoid. The other directly to the wastegate from the boost solenoid. I've tried putting a pill in the wastegate line, i've kept it out too. The stock pressure sensor is not seeing any pressure at all and is electrically disconnected.


My boost will peak at 5, jump to 10 and drop back down to 5 then vary in between all in the same gear. My system is bone stock. Stock intake, stock exhaust. However, when I got the car, it was boosting up to 10psi (read off of aftermarket gauge).

Please help me I need to know this will work before I put on a front mount and full exhaust.

 

I'm confused, is the car stock or not? You say it's stock, but also say the stock pressure sensor is electrically disconnected and see's no boost. Which one is it?
