This is a change to your rev limiter from OEM to a hardcut effect on your existing map. Very popular in the off road scene and comes with free membership to the pop and bang brigade ;-)

Take a look at the video for the effect.

Buy outright for a hard limiter on your existing map or select for free on the dropdowns when you buy a stage 1, 2 or stage 2+ from us.

Note: If you are unsure if you have a NNN ECU please refer to your engine number. This will start with 15p for NNN ECUs. As a guide, NNN ECUs came in around 2002. If in doubt give us a shout.
