The brand new MAXD-OUT Pro tuning handset allows you total control of your vehicles ECU calibration without the use of any Windows PC to switch maps. With over 5,000 MAXD-OUT devices across all platforms sold worldwide for various Ford models you couldn't be in safer hands.

This stage 3R version of the MAXD-OUT device to suit your Fiesta ST Mk8 contains a super safe engine calibration that runs a small lift in boost over the stock mapping but lifts torque and peak performance significantly by 90-105bhp and 100-120nm at peak levels to make the car feel effortlessly quick. The torque delivery below 2300rpm is very similar to stock meaning power isn't wasted away in wheelspin, once above this point in the rev range the additional power and torque is relentless and makes an incredible difference in day to day driving.

Not only has this tune proven itself to have the best performance increases available on the Fiesta ST Mk8 with a hybrid turbo, it also features unique features including on the road switchable mapping. Normal driving mode and Sport/Track mode have some very differing features that enhance the driving experience in a way only MAXD-OUT know how to do. See the table below for the available features which are customisable to your liking.

In normal mode the car is very much OEM+ with eco features enabled such as stop start whilst maintaining the performance everybody expects from the MAXD-OUT mapping calibrations. But hit the sport mode button and the car really comes alive with amplified crackles on overrun, sharper throttle response, more aggressive hardcut limiter, refined launch control and the full fat performance that MAXD-OUT has to offer!
