First I would like to say that Stratified has gone above and beyond my expectations - I have been tuned by them 3-4 times and have never found a reason Not to refer them to everyone whos considering a tune for their Mazda.

Stratified is great because they put down aggressive numbers that Nobody will complain with, however they do so making sure everything is very healthy and smooth and safe at the same time.

I have been E tuned for modded stock turbo, Dyno tuned for E85 stock turbo, and E tuned for Big turbo and Big turbo E85. All four tunes have been quick yet I have seen him putting in the time to do it right. Respectable - The owner Lex is a rad rad person to meet. Safe - I have pushed my car like a stupid kid trying to blow something up yet these tunes have been so reliable I can't seem to even provoke an issue with the car.

LASTLY -- Soooo Much Power. Whether you have a few mods or are heavily modded, Stratified is the way to go. The power gains Lex can pull from your car is amazing. Very Very reasonably priced (never take your mazda to a random local shop for a tune, twice as much, not as safe, lower numbers).

Also buy Stratifieds "Guardian Angel" to protect your engine. This is literally a Must.

I just completed my MS 3 tune with Stan from Stratified, and I couldn't be happier with the results.

My car is pretty mild and is my daily driver. I had played with the Cobb OTS maps, but was very nervous about the boost based tunes, especially since I live in the Midwest where the range of ambient temperatures is pretty broad. I was concerned with the potential for generating unsafe levels of power in sub-zero conditions and wanted to go to a load based tune, but obviously not the factory map.

I first tried the S-OTS+ map from Stratified and was immediately impressed with the improvement over both stock and Cobb Maps. It was not long before I decided I needed to step up to the full tune. I ordered the tune on the website, corresponded with @Lex; about what I was looking for in my tune, and was then put in touch with Stan.

Stan was very professional and knowledgeable throughout the process. He answered all my questions, and I learned a lot through the process. I wanted a tune with good drive-ability, and decent levels of power, but above all, piece of mind regarding engine safety. We found the limits for boost and timing and then made some adjustments to give me the margin I was looking for. The final tune is just stepped back a bit from the highest boost and timing targets that worked for my car, and the AFR is just a touch rich at WOT to ensure cylinder cooling.

In the end some performance was left on the table, but I have solid piece of mind that the car is safe, and operating correctly. Since we found the limits, and then backed off a bit to provide the margin I wanted, I feel completely safe to romp on the car everyday, which I do

The best thing about the full tune is that you get what you want and a tune that meets your unique goals. By working with the tuner to meet your goals, you gain a fuller understanding of what your car is doing, and where its limits are. I wanted more margin of safety than some people may desire, but now I know what I have and it matches my desires for my car.

TL;DR: My car is quicker than it ever was on an OTS map, drives great, and I feel completely confident that the tune is safe. Stan was completely professional throughout the process. I highly recommend Stratified, and will work with them on any future changes to the car.

Mike is the man when it comes to DISI tuning! Got some serious gains from a 93 tune. I'm addicted to seeing how much we can get out of this engine, so I'm going for the E85 tune today. Throughout the whole tuning process Mike was patient, knowledgeable, and explained things well. He dealt with everything in a very top notch professional manner. I will only use Stratified for my tuning needs. To me, there is no one comparable.

The ots+ tune is money well spent. It blows the cobb ots tunes out if the water. These are custom tailored to your specific mods, just do it! My ms3 feels so different now. Power comes on fast and smooth. Ive had no issues with my ots+ map. Dont hesitate, stratified tuners know what they are doing. You wont regret trying them out.

Killer pre-full tune map! Lex,Mike and the boys at stratified took me to another level. Although I'm not fully tuned (yet) the s-ots+ map they provided for me smoothed how my car reacts on acceleration as well as shifts. Power came on quicker and overall drivability improved dramatically. My long term fuel trims went from an erratic -/+13% down to a stable -/+4%! These guys know their stuff and just as importantly our cars! I highly recommend their services! YOU WILL NOT BE DISAPPOINTED!!

Car pulls like a mad man after the E-tune and working with Alex was great! Very happy and would recommend Stratified to anyone looking for a tune. I will be coming back for a E-85 tune soon!
