This system has been designed to be a “bolt on kit” thus allowing the vehicle to be returned to its original condition, if required.

To complete your installation, we also offer ancillary supporting parts including tuning aids, and engine management systems (ECU’S). 

PLEASE NOTE!

This product requires an after-market engine management system (ECU) for correct engine fuelling operation.

AT Power offer a choice of after-market (ECU's) which can be viewed on the ECU's & Wiring Looms page of our website, or by following this link ECU's & Wiring Looms

As with all after-market engine management systems, base maps are offered “as-is” and dyno tuning is fully recommended, to avoid causing any damage to your engine.
