Love the tune on my ‘14 focus ST. It was a great experience working with Fabrice Vieillesse. Always quick and happy to answer all the questions i had during the process. More than just custom tuning the car, the Stratified team also helped me gain a more in depth understanding of the ford ecoboost engine, what to look for on logs to make sure the tune is responding properly, and what the car is capable of.

The tuning process went way smoother then I expected thanks to my calibrator it was professional from beginning to end and OMG my focus st runs great !!!! I will definitely be back for my power upgrades thanks Stratified ...

Yo, i got my Cobb AP and signed up for a custom tune for my Speed3 Bk( or First gen )
I had somesort of "mom & Pop stage 2 tune" that gave me some problems with Fuelcuts during WOT.
The base map from my tuner, Duke Nolan, did immediately delete this problem by sorting out my EBCS and everything else.
We passed WOT logs back and forth and the end result of both my 98RON tune and E30 fuel mix is SUPERB! Both packs a good punch with my wishes for reliability also in place.
So practical and easy to via email send logs that makes your car just gain power for each week that passes, amazing really!
Or as Jeremy Clarkson describes the turbo spool, Witchcraft!
Every annoying curious question i had, Nolan answered and gave me light on my questionmarks!
So Spot on service!


So for the final words!
Tune is spot on, car doesent feel different besides when i punch it.
The only occational downside i had during my tuning process i had was that sometime it took up to 2 weeks to get a new log.
The wait time is unbearable when you just long for a mail from your tuner with new a revision.

Ofcourse i understand that Stratified is a prestige tuning company with many customers such as myself! So i can blame noone for having to wait a little extra time, Its totaly worth it in the end.
I will be back with new mods in the future!
Recommend to the fullest extension!

From Sweden, Robin!

The tuning process with Jared was very smooth. He responded quickly and i have zero complaints. The car feels great have about 10k miles on the tune. I definitely recommended stratified for a ProTune.

I'm happy with my ProTune. Both of them. The 93-octane and E30 variants.

The process was long for me. Alex, the tuner, had to work out ways to compensate for little drivability issues that were unique to my car which took many revisions, sometimes with long waits between them. But because the value of what I got feels so high, I don’t complain about the sometimes-long wait between those revisions. It's not like I was ever left with an undrivable tune - every revision was safe and good to drive on while I waited.

And from the very first iteration of the tune, it was fast.

When I got the Accessport, I tried the off-the-shelf COBB tune (Stage 1, 93-octane, High-Boost) that came with it, and it scared me. I was scared because it was slower than the JB4 piggyback tune I had just sold to buy the Stratified ProTune, and I was worried that the ProTune would be slower than the JB4 also.

Not so! The first iteration of the ProTune was three-quarters of a second faster than the Cobb tune, just through third gear (timed from 35-75 MPH in 3rd gear, starting WOT at 20 MPH).

I'm more enthusiastic and picky than most people about this stuff, which frankly stops me before recommending most products. Alex never made a mistake or did anything I felt was dangerous to the car. The car runs well and goes real fast. So I recommend Stratified, and Alex too.

just had my rs tuned by Jared and I cant say enough how awsome the car is now. It's like a whole new car you feel the power increase right away. Would highly reccomend to anyone looking to get their car tuned.
