2007 MazdaSpeed 6 (owned since new) - received base flash within a day; car has never run better. Let the fuel trims adjust, ran the logs and sent them in for review. Results indicated the car is good; with the tune from Stratified, car has never run better or stronger. Very highly recommend Stratified without any reservations.

I was just running cobb ots maps on my v3 and stratified literally blows them away in every aspect. Power delivery is much smoother and direct, throttle response is instant and the car is much more refined when just putting around town. This was just how the st should have came from the factory. These guys are also super quick, i ordered my tune around 3pm and had it by 7pm the same night. If your on the fence about which tuner to go with, look no further, these guy are the real deal. Cant wait to get my intake, exhaust and intercooler put on and then see what they can do. Im sure it will be awesome. Thanks stratified!! You just gained a customer for life!!

I had a great time getting tuned by Alex. He was quick to respond to emails and answered any questions I had very well. He made it clear to me where the car was progressing to and reached my power goal I was looking for. I had great service from a company I had never had experience with and they have earned my trust and I will definitely come back for anything I might need.

Absolutely no regrets! I spent MONTHS searching for the tuner for me, and I am super picky when it comes to my car. I went through my tuning process at the same time as a close friend, who was tuning with a different reputable tuner, and let me tell you! My experience made him jealous! He's now looking at tuning with Alex. At Stratified, they're extremely organized and detailed, and they provide you with all the information you could ever possibly want, and then some! Go with Stratified and you won't be disappointed! Thanks Alex!

I'm totally satisfied with the Custome Tune of my Mazdaspeed 3 Gen 2! Alex did a great job in tuning my daily driver which is fully bolted @ BNR S1 turbo and stock engine internals. He takes his time and explains the changes in every iteration of the tune.

I came to Stratified to have my gtx2867 powered focus ST tuned after I installed a WMI system to take advantage of the additional cooling and octane benefits. My car was transformed by Alex's tuning beyond my expectations. The difference in power after being tuned for the WMI felt greater than the going from tuned on the stock turbo to tuned without WMI on the gtx2867! One of the important things that is very apparent early on in the tuning experience with Statified, is how much attention is put into the safety of the tune. Stratified provided me with a greater number of revisions than the previous tuner I used, which allows smaller changes to be made in each revision, resulting in a safer way to finding the perfect tune. During the process, Alex was also able to help me determine the proper nozzle size, water/methanol mixture, and injection spray point. Stratified will continue to get my future business and I strongly recommend them to anyone needing tuning!
