mountune MR230 Performance Upgrade


Fiesta ST 2014-2019

This upgrade is for those that have already installed the mountune MP215 Performance upgrade.

As the name suggests, the MR230 upgrade kit delivers a performance increase to 230PS (227hp) at 5500rpm with 340Nm (250 ft.lb) of torque available from 3000rpm.

The MR230 includes a complete list of engineered components along with a revised performance ECU calibration to deliver maximum reliable performance. The MR230 upgrade includes high-flow silicone induction hose and intercooler charge pipe upgrade kit with our uprated alloy intercooler. Completing the upgrade we include our high-flow downpipe with 200-cell unit and a twin-tip cat-back exhaust system. All hardware can be added in a modular fashion except the downpipe, which is recommended to be installed together with the MR230 calibration.

mountune's engineers spent a great deal of time developing this kit to ensure that it delivers the optimum level of performance with the OE turbocharger, while maintaining the maximum possible reliability of the engine and transmission components. As part of the upgrade, the cam timing has also been optimized in the calibration. The revised cam timing provides a definite improvement in power and also helps hold on to the torque higher up in the rev range.

The end result is a very refined, OE-like day-to-day driving experience you've come to expect from a mountune calibration with an incredible increase in power and torque once you’ve increase to full throttle. The turbocharger spools into action, delivering a wave of torque that's difficult not to smile at, with an induction and exhaust note that's hard not to enjoy in equal measure!

For customers running the market-leading MP215 upgrade, the MR230 delivers a whole lot more of the same torque-related characteristics, but with a noticeably stronger top-end, and for those with a standard Fiesta ST, the change in performance is understandably, dramatic. Your mTune is easily updated in the field with the correct calibration that is sent to you once the upgrade is purchased.

With the kit installed, the 0-60mph time drops to 5.9 seconds, a full 1-second improvement over the standard model In-gear and midrange acceleration is improved upon even more substantially thanks to the 340Nm readily on hand.

  • mountune Intercooler Upgrade

5 of 5 "And though she be but little, she is fierce." September 13, 2016
Reviewer: Stanley Willis from Pittsburg, PA United States  
Wow!  Installed the MR230 Kit on my 2014 Fiesta ST and it absolutely rocks!  Tremendous extra power in the upper RPM ranges and an excellent boost in the already formiddable mid-range power band.  Looking forward to autocrossing this baby soon.  Couldn't be happier.
