Re: blowoff vavle

If the valve is open all the time you will not build any pressure. If the valve is stuck shut you will get pressure spikes when you shift, or lift off of the throttle.

What makes you think it is bad?

Re: blowoff vavle

Have you checked for leaks in the intake system?

It's not hard to make a boost leak tester out of PVC and a air chuck fitting from home depot/lowes, as long as you have an air compressor to use.
