Ah my misunderstanding. I was thinking to myself..."how is it that Rick of all people and all car knowledge, doesn't know about this?"

So out of

APS and TIAL are the only two BOV's I would recommend. APS has a 50/50

which has a better sound?

**Sinister** · 06-30-2010 09:11 PM

youtube them....

I'd assume TIAL since it's 100% atm and aps is 50/50 atm

**Turkey** · 06-30-2010 11:06 PM

So if i run the Tial i will have idle issues?

Tial is one of the better BOVs.

A valve that is setup properly and not leaking shouldn't have an impact on idle. Since the car isn't in boost, the valve is closed.

my Tial 50mm would crack open at idle, due to the vacuum load. it took a ton of spring pressure adjustment to stop that, then it would only open un after heavy boost, and not light, daily driven boost levels, such as in traffic, etc.

and my diesel, @ 40+psi, doesn't even use one

My father's truck has some severe compressor surge going... but ford claims it's normal

**Rogan** · 07-01-2010 09:12 AM

I think about 35psi.

it's not a variable vane/variable geometry unit, is it? they do wierd stuff on off-throttle responses.

I don't believe so... it's the 06 6.0L
