Gsport Custom Nissan daughterboards


Fully remappable Nissan daughter boards available now!!!


These boards are fitted inside your factory ECU to give the ability to fully custom map the ECU in the same way a standalone system would be tuned. All these boards are dyno tuned in house to get the absolute most from your setup.

Uprated injectors, turbos, MAFs and more can all be perfectly setup and mapped. ECU controlled boost can also be setup to do away with the need for external standalone boost controllers.


Prices starting from £399 which includes the daughter board, fitting, and mapping!!!
