Stratified offers customers the most complete custom tuning experience on the market for the MazdaSpeed and Mazda MPS vehicles. They have spent thousands of hours developing calibration maps for almost every setup imaginable through their custom tuning.

After filling out Stratified's tuning form, you will receive a Stratified Flash Tune via email within 48 business hours set up for the modifications installed on your car.

This applies to the intake (any intake on the market), fuel used (91 to 94 pump gas), and other flow modifications (Stage1 or Stage2). They can also clear any codes created by EGR deletes, VTCS deletes, etc.

** Now includes a complimentary MAF calibration to ensure that your car is properly calibrated for your specific intake. **

These maps are designed and extensively tested to employ Stratified's latest tuning strategies that they have spent countless hours refining. It is a great alternative to any OTS (off the shelf) map for your Mazda.

The Stratified Flash Tune is however NOT a fully customized tune. It is a flash tune adapted to work with your particular intake and flow parts. Stratified is NOT going to analyze logs, troubleshoot symptoms, or be responsible for any mechanical issues that may make this calibration incompatible with your vehicle. The Stratified Flash Tune is also not meant to be used with any bigger/aftermarket turbochargers or three port / interrupt style boost control solenoids.

If you are looking for a full custom tune specifically designed around your particular vehicle, fuel, and modifications, the Stratified Custom Tune is the next step. The custom tuning process is a one on one experience with a professional tuner designed to fully optimize the tune for your vehicle through data analysis and feedback.

E85 Mix Fuel Notes

If you have the supporting modifications listed below and would like to take advantage of alternative fuels and the performance they provide, we have developed E85 mix specific calibrations to cater to those customers who would like something above the pump fuel tunes. Please note that in the MazdaSpeed vehicles a mixture of E85 and pump fuel must be used. Using only E85 is not possible due to fuel system limitations so E85 and premium pump fuel must be mixed when filling up.

In order for your vehicle to qualify for an E85 mix map, you will need AT LEAST the following modifications. You must also ensure that your car is in tip top shape with maintenance that is up to date and no intake or boost leaks of any kind.

• Upgraded HPFP (high pressure fuel pump).
• Upgraded intake.
• At least one of the catalytic converters replaced with a test pipe.

Modifications beyond these do help performance but are not a requirement.
