Hello all! I recently bought a focus ST and found that it has a tune on it that was never unmarried. I know I am probably going to have to pay cobb to unmarry the car.

The 2 questions I have is:

I don't know if the car has a Stroker kit or a camshaft upgrade, Is there a way to know this without tearing everything apart?

Right now there is a plumb back BOV on the mystery tune that is on the car now, if I switch to dual port will this affect the mystery tune that is on the car now in any negative way?

Hello all! I just bought a Focus ST and I see it came with a compakt blow off valve. When I’m accelerating I hear the boost building up but doesn’t vent when I let off and make the pshhht noise, could this be because the blow off valve is turned a certain way and I need to turn it the other way?
