A friend of mine has a turbo czt and has problems with the blow off valve. when pressure falls the car stalls and gives engine light. did anyone solved these problems. same problem with the evc. need help please. thanks

try either of these 2 tips.
1) loosen the tension on the BOV by the adjustment screw,
or changing to a lighter spring.
this will allow for less air to be released.

2) if the BOV is a single outlet type, divert the outlet back to the intake,
between the maf sensor & turbo intake. these 2 ways of doing this will or
should solve your problem.

Dear friend bov is greddy s type rs . if ve return back it to intake can we get bov soud ?

thanks
