That would be great. Much Appreciated.
SO the BOV is the valve that releases the pressure built by the turbo after acceleration is done the aftermarket ones usualy vent into the hood of the car making a swoosh sound, the stock ones the vented air is routed through the rubber tubes and gose back into the intake(to keep the sound down) the purpose of this is possibly another way to make the car sound a bit more sport'y without spending the 700$. in theory this should cause no problems what so ever but always try at your own risk. U MUST plug up the ruber hoses because they lead to the air intake. if you dont and say drive down a dusy road the dust will get sucked into the turbo and well thats bad news. the turbo dose not require the air from the blowoff vaulves and the tubes are sealed by the vaulve when its not "blowing off". long story short TDIL take some hoses off, plug them up, get an ok swoosh sound thats lets people know u have a turbo without spending 700$. (again this should cause no problems what so ever but the whole reason to create this thread was to get some insight if it is 100% safe and share the info)(ps -i wil be geting the good vaulves but i need some side work first XD)I am new to turbo. Can someone explain why the tube is connected and why it is OK to be disconnected and capped?

Ok this might be a little long but bear with me. The valves that are installed on the Stinger are not Blow Off Valves, they are called Diverter valves. The main difference between the two is what their function is. BOV's vent excess boost pressure to atmosphere. They are designed to release the pressure in the intake system when the throttle plate is closed out to atmosphere, hence resulting in that swoosh noise that people chase. While on older cars that do not rely heavily on sensor inputs it has no ill effect on the car.
Diverter valves work on the exact same principle but rather then releasing the pressure to atmosphere it dumps it back into intake stream. This is done not to keep the sound down but to keep the amount of metered air the same in the intake system. As the car brings in air it passes the Mass airflow meter, the readings from this meter along with the O2 sensors determine how much fuel is released into the cylinders to maintain what ever the air/fuel ratio needs to be for the car at that moment.
So by replacing the diverter valves with BOV's or by removing their ability to divert air you are changing the the perceived value of air in the system. This will cause the car to run richer during off throttle moments, which will eventually foul the O2 sensors. Now i'm not saying this is going to ruin your car, i'm not saying not to do it. i'm just giving out some information as what the long term effects are.
This is correct if the sensors were installed ahead of the valves, in the Stinger all sensors are after the valves which means if it vents to atmosphere, the sensors will adjust for the air vented to atmosphere. In the Stinger whether you vent to atmosphere or to recirculate the engine will adjust for the air at the manifold not in the pipe work because the map sensor is right before the cylinders in the intake manifold.
I may have had 1 too many beers before that reply lol. Given it is a map not maf sensor, I doubt it would matter where it's placed, it's looking for pressure not volume of air so whether it's before or after valves in the looks or whether it vents in loop or to atmosphere shouldn't matter at all. What's really nice is map setups are a tuning dream, they are not as limited like maf setups. It's a an old/outdated setup option compared to maf but is more flexible for tuning options.Yeah it's nice that they did it that way. If it was in front, then we'd have problems that only tuning could fix.
