I have a 2013 golf gti coupe that i had bought a tune for. The difference between the COBB OTS tune VS the custom Stratified tune is amazing! My car doesnt even feel like my car at anymore. Its like a whole nother animal.
The customer service is 100% outstanding and more than helpful.
I am super pleased with this company and the way they have helped me and my car. I cannot say enough good things about Stratified!
10/10 will use again, and recommend everybody

I had the pleasure of working with Jared during the tuning process and was completely satisfied. For reference, my tune is a Stage 1 using 93 octane and the driving characteristics are perfect. It maintained the nice daily driving comforts down low, but now my car pulls hard when you step on it.

Now what I want to mention here are the benefits from getting a Stratified ProTune vs the other guys that we all compare numbers and reliability to. That was a choice I struggled with when choosing a tuner. Using Stratified instilled such a high level of confidence because I could communicate my wants/needs/concerns, actually see progression in the tune in each revision from the data and monitor knock, temps and boost through the Accessport.

One thing to note is that this isn't a "one size fits all tune" and there is a process to reach your goals. It takes a little bit of time (I believe Jared and I went through 7 revisions before we decided it was complete,) but you get a tune custom tailored to your car's quirks. I cant stress enough how beneficial this is. And if you see something you don't like (I had a little bit of knock in cylinder 2) you can reach out and discuss solutions/adjust the tune in the next revision.

Another benefit is the ability to switch off the tune if you need to. Going on a road trip and cant get 93? In less than 5 minutes your worries are gone. No need to carry a laptop or find a dealer to change. Active monitoring and ability to change maps is worth every single penny.

If your debating between the other guys and Stratified, get Stratified. You will not be disappointed.

I had the pleasure of working with Nolan on my custom tuning for my hydro Turbo on 91 with mild crackles and pops. Pretty straight forward process of uploading maps and datalogging. Was pleased with every map and stronger pulls to the end! Communication is key durung the whole process and the Team was very helpful in addressing/correcting any tuning concerns. I highly recommend! Love those crackles!

The protune through stratified was a great experience. Alex was very helpful and insightful. The improvements to the car exceeded my expectations, the turbo lag from the factory is dramatically improved as is overall driveability. Would highly recommend this service!

My tuner was very nice, very good at communicating and got the job done right! I have no complaints what so ever and the car is twice as fun to drive around now. Definitely worth the money!

Very very happy with the tune and the tuning process. Very fast. And my car feels like a rocket. And these guys know mk7s
