Overall, I am extremely satisfied with Stratified protune for my mk7 GTI. My, protuner Jared, was very helpful and responsive in regards to my tune! He was there and helpful every step of my tune. Initially, I suffered misfires, but he worked with me to make sure my spark plugs were up to spec, and continually adjust the tune to make sure. To go through 13 revisions of timing and boost adjustments speaks in volume how much they were willing to work with me to get me to where I want to be. I will be coming back to Stratified in the future for more tuning if I make any more adjustments!

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.

The whole tuning process was pretty easy. Directions from the website and tuner were very clear and easy to understand. Aaron helped me with my tune and my whole experience was positive. Every question I had was answered quickly and thoroughly. Im very happy with the performance of my Fiesta!

The entire process from start to finish has been amazing. Everything from the customer service from everyone I have talked to, to the tunes and customization of them. Even with my big turbo GTX2867R, the car drives much better than stock. The refinement and drivability are fantastic. During my tuning process I could feel every tune revision adding power, adding more refinement to everything from the way the clutch engages to the how boost builds up. The car pulls hard. Overall the tuning experience was more than I could have ever asked for. I will continue to use Stratified for all of my tuning needs.

I have had tunes from multiple companies and this is by far the best. Aaron is willing to work with you and makes sure the tune is exactly what you want. I also felt that they had the safety of my car in mind during the process. My car (17 gti pp) is much more aggressive now in all the best ways. Thank you guys for being a great company. I highly recommend working with Stratified, and I will in the future.

Absolutely could not ask for a better company to go through for tuning.
The fact that the techs was so quick in responding to my concerns and fixing the alight issue I had with a option for the tune. Cannot wait to get out and get my logs down to get my tune refined and looking forward to doing plenty more business with you guys.10/10 shout out to Nolan aswell you the man.
