The High Performance Diesel VNT Boost Controllers have been designed and created to suit: Nissan Patrol GU ZD30 CR's and DI's, as well as all vehicles with vacuum actuated turbo's. These Boost Controllers are made here in Australia with the quality and performance we have come to know from the HPD brand.

These Boost Controllers allow users to adjust turbo boost and therefore increase engine power, reduce turbo lag and create a linear boost curve. By also reducing boost spikes,the risk of 'over-boosting’ is minimised, which can be harmful to the turbo's internals. HPD Boost Controllers are perfect for those seeking greater control over engine management, are the perfect compliment for those with HPD Intercoolers and Catch Cans.
