I purchased both a regular pump tune and the E85 and BT tune options and have nothing but good things to say about both processes.

Through both the 93 map revisions and then later the ethanol mix, all of my questions were promptly answered and map revision turnaround was really fast, sometimes even the same day if I sent datalogs early enough in the day.

Stan was great to work with and all of my power goals were accomplished. I'm planning on re-tuning in the near future after I build and add supplemental fueling and I'll be coming back here when I do.

Alex was a great tuner to work with over the course of 9 months. He provided an outstanding 91 octane map (sea level) for my 2010 Mazdaspeed 3 (Stage II). He then worked with me to delay the continuation of further tuning until I was able to move to Colorado and get settled in. Then Alex was quick to help me with getting high altitude tunes for both 91 octane as well as E85 mix. I now run the E85 tune on my Speed 3 and really notice a huge performance boost compared from when I was running the off-the-shelf Cobb maps for Stage II. Alex's flexibility and professionalism was superb and I would highly recommend using Stratified for professional tuning. I will continue to look to Stratified in the future as my needs change. Thanks so much for creating such awesome maps for me!

Very grateful for Alex's expertise and patience! I was at 188,000 all original miles on my 2007 Speed3, and then finally upgraded to a BNRs3v2 with other supporting mods, and began the tuning process with Stratified. Many careful iterations later, with a 4gal mix of E85, my car is running better than I had imagined! I hit all my goals and then some - but of course now I am developing new goals. :-) Currently at 210,650 miles, and running very strong! Thanks, Alex!

Just finished the custom tune with Alejandro who was very helpful and informative throughout the process of the tune and answered many questions that I've raised about my car.

The car drives much harder and better! and I can really feel the difference from when I've started to how it is performing now.

I wouldn't hesitate to recommend Alejandro to anyone that's on the fence with the custom tune :)

They work with you to get the tune "you" want. Very helpful, and a great knowledge of the Speed3 engine. The tune came out better than I expected!

If I could give more stars I would! My car feels like a completely new beast! I didn't think much could be pulled out of the car but the E85 tune that Stan set me up with it's a night and day difference. I really appreciate Stan working with me since my car had to be sent back to the shop during our tuning process. The whole process was truly a great experience and I will definitely be back for another tune in the future. Thanks again!
