With my recent new tune, I am very happy with the feel of my car and the service I received. With each tune, Alex brings many years of experience hes gained developing the platform. His active engagement in the forums ensures the latest developments are applied. The company (from what I can tell) supports multiple car platforms through tuning and hard parts with limited man power, but still manages to deliver personalized service that comes across as genuine interest for you to achieve your goals. For the amount they charge for what you get, going Stratified is a no-brainer.

I have been working with Mike from Stratified since late Feburary on 2 different tunes. The first tune was a 91 octane custom tune, the second an e-85 tune. Let me begin with my mod list, cxracing fmic, autotech hpfp internals, UR turbo back catless exhaust, CS SRI, NGK 1 step colder plugs, Cobb AP V2, Synapsis BPV and JBR RMM.

My car always felt fast but was never really smooth, always felt "Raw." Mike changed that immediately. The idle improved and the power delivery was more consistent. Through the process Mike took my car from a beast from 3000-5000 rpms to a freight train that just keeps pulling. It never seems to falter, constantly pulling all the way to redline. Torque is abundant and willing the break the tires loose, my sticky Michelin PSS, in 1-3 gears.

What is so great about what Mike did was how much smoother he made the car all around. Before,if not driven perfectly it was like being in a rodeo, now the throttle in more forgiving and less temperamental. During the process we had 2 issues come up, a boost leak and somewhat of a misfire. The first, Mike noticed something in one of the logs and immediately diagnosed the problem, leaking bpv. He suggested the Synapsis BPV and arranged it getting sent through Stratified at a great price. Problem, solved. The second issue occurred during a trip. I told Mike the symptoms and sent him a log, boom suggested I pull the plugs and inspect. Problem solved, drove through rain storm water made it past cylinder 1 coil. Problem solved.

While the tune was great and worth the $ alone, the knowledge Mike passed on was worth even more. I don't frequent the forums often, there is ALOT of bad info on there, so it was refreshing being able to get a straight forward, correct answer. He gave advice on future mods, helped correct drive-ability issues, and explained what I should look for in the future to monitor my vehicle performance. He would make changes to the maps and requests logs. I would send the logs back and with in a day or so, sometimes a few hours he would have the new map sent and the process would continue.

I am extremely satisfied with this purchase and will be continuing my tuning experience with meth and a BT, via Mike.

I purchased both a regular pump tune and the E85 and BT tune options and have nothing but good things to say about both processes.

Through both the 93 map revisions and then later the ethanol mix, all of my questions were promptly answered and map revision turnaround was really fast, sometimes even the same day if I sent datalogs early enough in the day.

Stan was great to work with and all of my power goals were accomplished. I'm planning on re-tuning in the near future after I build and add supplemental fueling and I'll be coming back here when I do.

Alex was a great tuner to work with over the course of 9 months. He provided an outstanding 91 octane map (sea level) for my 2010 Mazdaspeed 3 (Stage II). He then worked with me to delay the continuation of further tuning until I was able to move to Colorado and get settled in. Then Alex was quick to help me with getting high altitude tunes for both 91 octane as well as E85 mix. I now run the E85 tune on my Speed 3 and really notice a huge performance boost compared from when I was running the off-the-shelf Cobb maps for Stage II. Alex's flexibility and professionalism was superb and I would highly recommend using Stratified for professional tuning. I will continue to look to Stratified in the future as my needs change. Thanks so much for creating such awesome maps for me!

Sincerely,

Very grateful for Alex's expertise and patience! I was at 188,000 all original miles on my 2007 Speed3, and then finally upgraded to a BNRs3v2 with other supporting mods, and began the tuning process with Stratified. Many careful iterations later, with a 4gal mix of E85, my car is running better than I had imagined! I hit all my goals and then some - but of course now I am developing new goals. :-) Currently at 210,650 miles, and running very strong! Thanks, Alex!

Just finished the custom tune with Alejandro who was very helpful and informative throughout the process of the tune and answered many questions that I've raised about my car.

The car drives much harder and better! and I can really feel the difference from when I've started to how it is performing now.

I wouldn't hesitate to recommend Alejandro to anyone that's on the fence with the custom tune :)
