Symptoms of a bad bypass valve?
So I'm thinking that my bypass valve may be bad due to some things that I'm seeing. There seems to be an unusual amount of play in it when I move it vs moving the one that came with the harrop TVS. I'd switch it out but the one that came with the harrop doesnt allow for boost cut through hp tuners.
Some other things that have been an issue is higher IATs, when I first put it on the TVS I was getting a bypass valve code but then it went away. I seem to be missing about 3psi or so. Car doesn't seem to have the same punch it did before.
So what are some typical things that would indicate its bad and I can confirm if thats what I'm experiencing or not?

lower or flucuating boost
whacky afr's
Decrease in fuel economy
those are the most common things to indicate if it is bad.

I have all of these symptoms but no Harrop.
I have been thinking for awhile that my stock Bypass Valve and or Solenoid is going bad.
What parts do I need to buy to replace it and where do I get them?
Thanks for your help.

how would you limit boost with the harrop bypass valve? theres only one line on it and that goes to the charger theres nothing to hook the other line to the solenoid

To my knowledge you can't limit boost on the harrop becuase it comes with the acuator that has the provison (2nd port) removed as the did not deem it neccessary.
