All:

I bought ModaWorks VTAs for the M276 SL450 (a twin turbo V6).
One of the sides, whether through improper installation or otherwise, began to leak boost.
So I removed it. Basically, stock on one side, a VTA on the other side.

I'm now wondering if this is okay -- do I really need both VTAs as they have minimal effect in general?

Thanks,
Ransom

ygmn

all they do is let you hear the air pressure release noise not much else they do...
I am wondering why get them at all? just for the sound?

Your VTAs are probably screwing up your A/F ratios and driving your ECU crazy. Have you ever gotten any DTCs or CELs? I know the "boy racers" in the Subie world like them because they sound cool, but I haven't heard any in a while. Not sure they are even legal in this era of environmental protection. They are not looked upon favorably in some tuner communities.

I would say you need none, but certainly not just one on a car with twin turbos. I like to have everything in balance and while it may not hurt anything, I wouldn't chance it.
