#96216, "RE: How do I choose the right Wastegate and Blow off Valve?" In response to In response to 1
I agree with everything rhui said but would like to add that it is ok for us 420As to vent the BOV to the atmosphere, we use a MAP sensor and not a MAF like the factory turbo guys.
Theres nothing wrong with the deltagate you have now but if you got the money tials are pretty.
