Do you need a tune for a GFB BOV?
A bone-stock car, or one that has been modified AND tuned will usually be less sensitive, often allowing up to 100% atmosphere venting without issue. This is because increasing the airflow (via increased boost, free-flowing exhaust or intake etc) without tuning the ECU to suit will usually result in rich mixtures.
What is a GFB diverter valve?
GFB’s DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles. By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-orientated product.
How do I make my GFB BOV flutter?
If you want your BOV to flutter a bit, try increasing the spring preload by turning the adjustment clockwise. It’s perfectly safe to set your BOV up to cause some low-rpm flutter, as long as it vents with a whoosh at high-rpm and boost.
How do I choose a BOV?
‘ The first question is easy to answer: There isn’t actually a ‘best’ in terms of quality. All GFB blow-off valves use the same high-quality internal components. So, provided the right BOV is fitted for your particular vehicle, they all offer the same performance benefits of improved throttle response and reduced lag.
How does GFB DV+ work?
The GFB DV+ uses the factory solenoid coil, but its role is to control the pressure signal used to actually open and close the piston, which is known as “pilot actuation”. This means the forces that the solenoid coil deals with are much lower, and its operation is therefore reliable at much higher pressure.
What is a GFB VTA?
The VTA is a performance blow-off valve solution for Audi, VW, Skoda and SEAT vehicles with an electronic factory diverter valve. If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that!
Does a BOV add HP?
The MS3’s bov leaks at stock boost levels. Going aftermarket does not add any more power, but stops the loss of power due to the leak. This is not the case on our cars.
