Go Fast Bits VNT/VGT V2 Universal Diesel Boost Controller. Product Info: Want to increase or decrease the boost on your variable vane (i.e. VNT/VGT) turbo diesel? Is the factory boost curve erratic and all over the place? Blown an engine with the factory boost control system? Then the V2 is for you! It’s common knowledge that some engines with vacuum operated ECU controlled VNT/VGT turbos suffer erratic boost behaviour, 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 aluminium 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.
