The 300ZX Turbo responds to boost and tuning the factory ECU was never built to deliver.
The Nissan 300ZX Turbo is a capable platform, but factory engine management puts a ceiling on what's possible. The Boomslang PNP Wiring Harness 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.
Advantages
- Boost that builds and holds exactly where you dial it in, not where the factory knock strategy allows
- Timing that advances where it should instead of pulling at the first sign of heat
- Power delivery that's linear and predictable through the entire boost curve
- A tune built around your exact modifications, not averaged factory parameters
- Confidence that what happened on the dyno is what happens on the track
