At first I started off with an OTS+ tune and I was definitely satisfied. About a month after using the OTS+ tune I decided to go with a custom e-Tune, for the added safety and power, since I do not plan on a big turbo for my Focus ST and have all mods completed (aside from a downpipe). The feedback from my tuner (Steven) was fantastic and he was willing to answer any and all questions. The power delivery, drivability, and overall quality of a Stratified OTS+ and custom e-tune are fantastic. Originally, I chose to go with Stratified thanks to a few friends in my local car club and for the amazing article Alex and the team write up on their blog site. Stratified automotive employees are engineers, professionals, car nerds through and through and extremely knowledgeable. I would trust them with any vehicles I own in the future.

Coming from an STI, I had pretty high expectations from a tuner since the person who tuned that car was great. Before deciding on a tuner for my Focus I did a lot of research on the tuners available for this vehicle and settled on Stratified because I read they were very thorough with their tunes and wouldn't leave you hanging. I was not disappointed, I ordered my AP and tune sometime in the middle of June and about 6 iterations and a month and a half later, we were done. We actually went over my allotted time but Alex felt that my tune wasn't complete and requested more logs so that he wouldn't leave me with a half baked tune, so huge props for that.

As for the tune, I put every datalog I took into VirtualDyno to get a good idea on my progress. I'm not too sure on the accuracy of VD, but I used it mostly to quantify my progress. My car started at around 205hp and 280tq to the wheels, according to VD. Each iteration I saw more progress and better drivability. At the end of the tune, I am at 241hp and 330tq and the car pulls like a train all the way to redline. Boost comes on easily and power delivery is very linear and I notice no plateau in the powerband at all. Iv also noticed better MPG over stock, as well. I'm very satisfied with the final revision.

I can't wait until Fall when I'll have more parts and see what else they can get from these little engines.

Alex is probably one of the most knowledgeable tuner out there for our ST platform. He takes his time and really tweaks and perfects every revision for max power safely and efficiently. You will not be dissapointed in a custom tune from this stratified.

The Stratified custom tune process and end result were both terrific. Alex's efforts were always guided by my tuning goals, and it was particularly gratifying to see my parts selection validated by some big numbers, superb drivability, and safety margin as evidenced in all of my datalogs. In my opinion, no one understands and tunes the ST platform better than the Stratified team. Alex's engineering background shines through in his tuning approach and drive to innovate. On top of all that, he is a very nice and comfortable person to work with. I give Alex my highest recommendation, and feel that my Stratified custom tune is a tremendous value given the effort Alex expended to perfect it!

I decided to have Alex tune my Ford Focus St based on the great reviews found in the forums. All I can say is that Alex loves to perfect the tune and is very educational when answering questions that I asked during the tuning process. Overall I am very satisfied with the results and wouldn't think twice about using his services.

Alex at Stratified delivered exactly what I would have expected. He listened to any of my concerns and addressed them right away. The power delivery is there and smooth even when my car has minimal mods.
