GFB D-Boost V2 VNT Manual Boost Controller

’s common knowledge that some engines with vacuum operated ECU controlled VNT/VGT turbos suffer erratic boost behavior, to the point where turbo or engine failures can occur, even on completely stock vehicles. The V2 takes over from the factory ECU control and ensures a stable and repeatable boost curve, which your engine will thank you for!

Cleverly packaged within a black anodized CNC-machined 6061 aluminum housing are two individual adjustment dials, each having a separate and unique adjustment function.

This first dial sets the boost pressure, whilst the other is used to adjust the boost rise rate, i.e. how fast the turbo spools, meaning you can tune your boost to suit any driving conditions.

PLEASE NOTE:

Any form of boost control should be considered a tuning tool rather than a bolt-on power adder, and therefore adjustments should be done with a boost gauge, appropriate fueling, and knowledge of the limits of the engine/turbo to maximize the performance gains and reliability from using this product.
