With the MBC i just tapped it into a hose. (as the instructions said)
It's the vaccum line running from where my intake piping goes into the turbo(small nozzle under compressor side) to the wastegate.
I did no other altering of anything in my engine. (other than making my BOV into an atmospheric dump valve instead of recirculating)
And as far as the MBC's setting goes, ever since the over-boosting, i tried setting it to it's lowest boost setting, and it still overboosted.(same deal with engine temperatures)
right now i have just a standard vaccum line running where it should be. (so it's stock)...Still overboosting....could it be the temperatures here?
It's been around 15 degrees Fahrenheit here....(COLD!!!)
Could it be the MAP sensor?
could it be that the wastegate is....broken? it seems the be functioning right, the rod moves when i push on it. (with a bit of force)
