Excellent value for the money. I really can't see why you wouldn't spend the extra money to get the most from your upgrades. Stratified works with you to get what your after in a safe manner. I'm stoked on the results which netted a 18-20% increase in hp/tq that you can really feel.

If your going to add aftermarket parts, go with Stratified!

Had an awesome tuning experience with Alex. Top notch customer service, every question was answered even some not related to the tune. Responds quick to emails, also added time for days missed with out needing the customer to remind. Provided customer with a great learning experience. Willing to work with Stratified tuning for my next project. Recommened to all Mazdaspeed platform.

I cant say how pleased I am with my Stratified tune. Hands down, best money I have spent on this car. The hp/tq gain per dollar far outweighs any other mod you can do. Lex is extremely knowledgeable about the platform (with more than just tuning, this guy know every inch of the mazdaspeed 3). He progresses your car at a very safe rate, never putting your car in danger. Without a doubt, I would recommend Stratified Tuning to anybody looking for serious power without breaking the bank.

I purchased this tuning package from Stratified. I am super happy with Lex, he went above and beyond what I was expecting. I learned quite a lot in the process. I recommend Stratified's service very strongly.

Stratified Automotive Controls was amazing in this process, Alex was very clear in his instructions and was always willing to help with any of my questions. Outcome was a siginificantly faster and more fun car to drive.

The process on my end was really easy; log, load, go faster. I'd recommend this to everyone with a speed3.

The process could not be easier. The end result is power gains throughout the whole rev range and smooth at that. Alex was fantastic in answering all my questions and helping through the modding game. Would I go through this process again? Yes yes yes.
