Anyone know could after market BOV cause increased fuel consumption?

I've installed Stealth FX last summer, and sometime as of last summer my fuel consumption has been ~20L/100km.

Changed O2 sensor, still the same
Cleaned the injectors, same

When i was at Sports and Luxury, they couldn't find anything.

I just don't what to do, fuel is just running out the exhaust, when i hit the pedal i leave a cloud of smoke.

I noticed that as well when I put my aftermarket blow off valve on my old car. But I swapped out the O2 sensor before hand and it didn't make a difference so I thought f*^k it and fitted the blow off valve anyway.

So did you find out was it the BOV causing the problem?

I heard that with MAF sensors, the vented boost pressure is still calcuated when adding fuel and causes vehicles using a MAF to waste more fuel.

But all the 1jzs use a MAP sensor, so i don't know.

I haven't had any problems with fuel consumption since i put mine one.

Hey, guys does anyone have a photo of stock BOV connected? so i could try to put it back on, to see if that is the problem.

On the StealthFX there are two hoses connected, but when i looked at the stock bov, there are tree plugs, so i'm a bit confused.

Here's the photo, x marks the hoses (judging by the size) connected on the StealthFX.

Mr T told me that when they were perving under my bonnet.

Isn't the 2 thing a Vac thing. Like what you connect a boost gauge thing to. I forgot what they are called.
