The Ford Focus ST is an extremely popular model with good reason! Impressive power and torque delivered to the front wheels provides a lively and exciting driving experience with fantastic all-round performance.

Custom Tuning is available NOW from MRT Performance using EcuTeK software and delivering next level performance, with official MRT Power Kits not too far away.

Every engine is slightly different, and unlike other tuning products available on the market which use “Off The Shelf” maps which are not specifically tuned to suit your individual car, at MRT Performance we take the time to custom tune your individual car, guaranteeing you the best and safest results!

To give you an idea of the results we can achieve by custom tuning the Factory Engine Control unit, here is a dyno graph showing a stock car VS. MRT Tuned car with NO other physical modifications…..

Focus ST Custom Tune WITH Exhaust

Hi Brett,

Sorry it has taken me so long to give you some feedback about how the car is performing, the last few weeks have been very hectic for myself and have not had the opportunity to properly drive the car.

Overall the car is performing flawlessly I cannot fault it in anyway possible since you have done the tune to it.

Initially the car did seem a bit sluggish compared to the Cobb tune when you would really put your foot down, where that seemed very quite brutal in its initial power delivery from 2000rpm,

But with your ecutek tune, it’s a lot more relaxing while putting your foot down it doesn’t feel as if you have overwhelmed by the power but is very consistent in it build up through the rev range.

Ultimately I can definitely tell their has been an increase in power especially at the back end of the rev range, even around the 5000rpm mark the car is still accelerating very quickly and feels like it has more to give.

I am extremely pleased with the work you have done to the car it absolutely fabulous, with the power delivery being so much more controllable and also the torque stear is vertically unnoticeable,

I look forward to what I’ll be able to do with the car at the next rally sprint
