I changed the vacuum lines( most of them)
I have 3 BPV one new Forge 007
ne new 710Nne old stock valve with a partly brocken vacuum niple.
If I put any of the new ones on I loose boost @3000RPM.
If I put the old one, or I unplug the vacuum line on the new ones I have boost like crazy, with some surging, but it puls right up to red line lifting the front of the car, lots of power.
I know I shouldn't be unpluging the vacuum line but if I put the line on I have no power after 3000RPM.
What can be done ? Why is this happening?
