The 3000GT VR4 is one of the most technically ambitious Japanese sports cars of the 1990s, and the twin-turbo 6G72TT responds exactly the way you'd hope when standalone ECU management replaces the factory unit.
The Mitsubishi 3000GT VR4 6G72TT is a platform with a serious following and real tuning potential, but the factory ECU has always been the limiting factor. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
