Alex did a great job with my 2017 WRX. He was quick to respond and when I ran in to some problems he help me solve them and adjust my car to the perfect tune. My car runs so smooth now. I would highly suggest Alex when it comes to tunning your car.

Yo, i got my Cobb AP and signed up for a custom tune for my Speed3 Bk( or First gen )
I had somesort of "mom & Pop stage 2 tune" that gave me some problems with Fuelcuts during WOT.
The base map from my tuner, Duke Nolan, did immediately delete this problem by sorting out my EBCS and everything else.
We passed WOT logs back and forth and the end result of both my 98RON tune and E30 fuel mix is SUPERB! Both packs a good punch with my wishes for reliability also in place.
So practical and easy to via email send logs that makes your car just gain power for each week that passes, amazing really!
Or as Jeremy Clarkson describes the turbo spool, Witchcraft!
Every annoying curious question i had, Nolan answered and gave me light on my questionmarks!
So Spot on service!


So for the final words!
Tune is spot on, car doesent feel different besides when i punch it.
The only occational downside i had during my tuning process i had was that sometime it took up to 2 weeks to get a new log.
The wait time is unbearable when you just long for a mail from your tuner with new a revision.

Ofcourse i understand that Stratified is a prestige tuning company with many customers such as myself! So i can blame noone for having to wait a little extra time, Its totaly worth it in the end.
I will be back with new mods in the future!
Recommend to the fullest extension!

Alejandro was awesome! He pretty much always replied within 24-48 hour with answers back to me. He did a great job tuning my GenWon MS3. Made huge power gains Compared to the OTS tunes. He worked with me for a couple months until everything was perfectly dialed in. I would recommend him 100%.

I am extremely happy with my big turbo custom tune. So far the tune seems incredibly safe, only seeing 1-2 knocks on WOT pulls. The car is making very good power for the setup right around 400whp and 400tq according to vdyno.

The only downside to using stratified, in my experience, was that there was sometimes a week or two delay between sending logs and receiving the next iteration of the tune.

I cannot complain too much though as each revision of the tune performed much better than the last, and i did not receive one unsafe tune.

All in all i am very pleased with the service and experience procided by Alex.

Purchased this custom tune after hearing great things about Stratified from the Mazdaspeed forums. Was not disappointed! The tuner was professional and thorough, and the tune totally woke the car up. I would absolutely go to Stratified for custom tunes in the future!

The tune I got from stratefied is simply amazing. My car pulls harder in every gear and is much faster and smoother. I highly recommend them to anyone that wants to get the most out of their car. Now to go get on a dyno.
