I just threw my brand new 44mm Tial BOV on my evo lastnight and now all I'm getting is compressor surge because it's staying stuck shut... what can I do to get it to open? It's running 22psi and I thought it came with a 10lb spring but I'm not 100% positive I guess I'll have to take it all apart and figure it out, but I was wondering if you guys have ever had any trouble with this or tips on how to fix the issue...

Could I just wd40 it? lol!

 

Do you have it hooked up coreectly to a vacuum source?

 

You mean wastegate bov comes only in 50mm

 

Adjust the spring ???? Maybe its on too hard? Did you hook it up correctly?

 

Are you referring to the waste gate? Also check the spring if it's not opening.

 

Tial 50mm bov has no adjustments......

First off, what Tial unit are you referring too?
44mm ~wastegate
50mm ~BOV

Check your vac and/or boost lines to be sure they are clear.

 

are you on the AEM or stock ecu cos if ur on the stock ecu u got to get the extra spring option that tial offers supposly

 

if you bov is actually sticking then use some silicone spray on the diaphragm. that was i used to do to my tial

 

the spring in your bov is too stiff

what does the car pull for vacuum at idle?

what size is the line you are running to the BOV? is it T'd off anything else?
