Tuning options and performance upgrades

JFN Tuning is developed, designed and tested to the highest standards to ensure that our customers receive the best engine tune upgrade for their vehicle.

The software is re-written on your engine’s ECU, enabling us to safely gain power and torque, which gives improved driveability with the added bonus of enhanced fuel economy on diesel engines.

We don’t believe that one size fits all; a vehicle’s performance and requirements change according to its intended use.


Economy Upgrade

2014-SEAT-Ibiza-Green jfn1

This option is designed to improve economy of turbo diesel engines.  By reprogramming the torque limits on the engine at lower RPMs you’ll notice improved economy, as well as benefitting from additional performance.

At high RPMs the software upgrade will encourage shifting up through the gearbox which enables the engine to keep running in its optimum window. This is the most popular choice, particularly with fleet owners and where extra MPG improvements reflects on bottom line profit.

Ecopower Upgrade
