I apologize for this question, but again I am new. i was wondering why is it when I get on the pedal in my EVO IX SE that I do not hear the blow off valve on my car. IS it because it is in an internal BOV? I mean I can here it spool and a little whistle but I do not here it like the turbo off other cars. That have exernal BOV's.

 

because our bov are recirculated. if you like to hear the bov between shifts get a cone filter and a tune.

 

Do I need an all wheel drive dyno to tune the car?

 

dude just get a Injen Intake W/Upper IC Pipes and the stock BOV will sound nice trust me i know

 

ehh i have it, its good and all but after awhile the bov gets ANNOYING!

 

not for a tune. here is a good link for you http://72.249.29.2/mellontuning/inde...s/Page396.html

 

Searching will answer a lot of your questions. A cone filter will let you hear bov and the turbo a lot better

 

 

You wont hear the stock BOV all that well, it does make a sound but it is very quiet.

What is your mods?
Are you tuned?

Do you need help to find good tuners?

 

I can hear mine with the Works drop in filter. Going to get Injen soon... hopefully its not TOO loud.

 

You should use a dyno. Preferably a load bearing dyno like a Mustang Dyno so they can tune part throttle, decel, accel, etc... If you needed glasses, would you order them online, or go to the eye doctor?
