The Japanese-market GTO twin-turbo is the same engine as the 3000GT VR4 by another name, and it deserves the same tuning attention.
The Mitsubishi GTO 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.
