Smooth and strong May 18, 2015
Reviewer: Hunter from Louisville, KY United States  
Parts that make up the kit are top notch. Being a daily driver, reliability was a big part of why I chose Mountune. Install was easy and only took about 2 hours. Power increase is noticeable from idle through the rpm range but really shines in the midrange. Turbo response is a lot faster but the car is smooth all around.

Only Mountune parts will go on this car! Proven quality!

MP275 Package December 31, 2014
Reviewer: Bob from NC United States  
This tune really lets the Focus ST lay down the power coming off the line, instead of making your tires go up in smoke. The WOT pull is addictive, and is strong up top where many other tunes peter out. The MP275 tune's enhanced drivability really surprised me, and lets the driver concentrate on things other than how much throttle to apply at any given time. And make no mistake - it's fast in addition to being very tractable!

MP275 October 29, 2014
Reviewer: Kevin Kearney from New York  
The quality of this upgrade is very good and the power is even better. I'm not sure what mountune did but the power does not fall off in the higher
rpm range like the stock car does and the overall power is strong. I would recommend this to anyone looking for a solid upgrade that takes the guesswork out of upgrading your Focus ST.

MP equals MORE POWER October 27, 2014
Reviewer: Geoff Spencer from Los Angeles  
The MP275 upgrade is awesome. The power delivery is so smooth and keeps pulling to redline. I wish I would have done this upgrade sooner. The quality is over the top and
everything fit like a glove. This is a well engineered product and not an aftermarket tuning project. I highly recommend this for those that want the best.
