From start to finish, with each map, the car felt better and better.
Each map modification was done so carefully and meticulously, to ensure the safety of the engine with maximum performance. Alex knows whats best!

My experience with Stratified Controls was a long yet pleasant experience. I started my tune on a SoCal NATOR Dyno day with a mildly bolted MS3. After discussing my options with my Tuner, Alex, we waited until I had all of the upgrades installed before continuing. Once we started tuning, I had quite a few mechanical issues which Alex was able to help me with. I decided to go with a stealthy Smog friendly setup that involved a BNR Stage 3 turbo, a TMIC, Grimspeed EBCS, Stock exhaust equipment, crappy California 91 Octane, and the dreaded summer heat. Multiple revisions had to be made over a 3 month period since my setup was extremely difficult to tune. Every revision felt like Christmas morning and making the logs was a lot of fun. In the end, I had all of my mechanical issues dealt with and a quick spooling 30% E-85 tune with a tractable power curve that allows me to drive with confidence in the canyons but still have a nice punch in the straights (and slightly better gas mileage than stock). If I had to do this again, I would not hesitate to do this all over again.

On a separate note, get the Guardian Angel. Only a fool would drive around unprotected.

So you are probably reading this to see if Stratified is the right choice for you. I'm going to guess that we are alike and only put top brand/quality items on our car. Stratified is no excuse, these professionals’ hands down know every Byte of the ECU.

The process it self was how all tuning should be. Alex was able to answer all of my questions, and follow all of my requests of how I wanted my car to perform. The car has gained more power from the tune then all of the mods I have done. The car feels great throwing me back in my seat every time I hammer the gas. There is no way around getting a tune for your car, its going to be needed it you want the top performance. Alex has stepped up my performance farther then I expected, Stratified is the way to go hands down.

When people ask for my list of mods, I give them the quick answer "Stratified."


EST gains(by Vdyno) 30hp/45tq

L'expérience a été extraordinaire.

Alex est très consciencieux et travail avec nous pour savoir ce que nous voulons sur notre SPEED3.

Ma voiture développe maintenant 330hp / 392tq avec de l'essence 94 octane.

C'est complètement une autre voiture. La puissance devellopée est très progressive tout le long de la plage moteur. Toutes les modifications que j'ai fait sur ma speed sont exploitées au maximum et ça parait.

Aucun KR, WG % est très bon et je vais jusqu'à 21 psi en LOAD.

Alors vous avez quelques modifications sur votre speed3 et vous voulez que tout roule à la perfection. Je vous conseilles STRATIFIED. Pour un travail de qualité, un service #1 et la simplicité d'exécution.

UN MUST !!!!
go for it

Great 1/3 E85 tune! Alex did a great job doing a top tune on my 2007 mazdaspeed 3. Explains everything really well. Car runs awesome. The process went smooth by email. Highly recommended!!!
Thanks again, Rick

My car had a horrible tune from a local tuner by me who was not to knowledgeable with the Ms3 platform. I was referred to Stratified tuning by Jp Alonso from Edge Autosport. I quickly got in touch with Alex, who rite away started helping me with my tune. Alex went above and beyond for me and my car. He was very quick with emails and answered all my questions I had to ask. He tuned my car on 93, and a E85/93 mix. Made my car over 400whp. Im so happy with the tune and the whole experience I had at Stratified. He will definitely have me coming back in the future for my next mods! I would recommend Stratified to anyone who has a Ms3 platform!
