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.

The Stratified custom tune process and end result were both terrific. Alex's efforts were always guided by my tuning goals, and it was particularly gratifying to see my parts selection validated by some big numbers, superb drivability, and safety margin as evidenced in all of my datalogs. In my opinion, no one understands and tunes the ST platform better than the Stratified team. Alex's engineering background shines through in his tuning approach and drive to innovate. On top of all that, he is a very nice and comfortable person to work with. I give Alex my highest recommendation, and feel that my Stratified custom tune is a tremendous value given the effort Alex expended to perfect it!

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!

Good investment for an above basic tune. COBB OTS stuff just does not compare. Drive-ability is vastly improved. Slightly more power as well. Worth the $50 easily.

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!

I got to work with Mike on my tune. He did a great job and I will be coming back for a top off when the new mods arrive. Car runs like a beast! Thanks again Mike
