Product Details
VW Turbo diesel VNT TDI
Boost spike is a major issue with the VNT diesel turbo system. Back pressure or excess fuel can cause the boost to rise faster than the VNT turbo's vanes can react,compounding this problem is the soot that tends to accumulate with age and causes restrictions in the catalytic converter or exhaust Spike and surge can cause the ECU to react by pulling out timing from the motor, this results in lower torque output and driveability issues.. By installing the TDI BoostValve this excess boost can be reduced.

The VNT BoostValve setup is NOT intended to raise max boost but to control spike/surge and effectively give better control of the turbo's wastegate.

Reduces surging and dangerous boost spikes.
