Great experience and easy to install. I installed a K04 turbo in my 2011 GTI and from the base tune all the way to the final revision was overall a smooth process.

Stratified just completed two fuel maps for E30 and 91 octane...K04-x with Aux Fueling installed as well. My tuning experience was very thorough with Jared Hughes working as the calibration engineer, he's responsive and provided good guidance related to overcoming some fueling limitations I ran into on E30. Each tuning iteration built well on the previous one during the process...no surprises...car runs great!

The tune exceeded my expectations... silky smooth when driving normally, but turns into a monster when you want to mob. Jared was great to work with and helped get the most out of my K04!

From my very first tune ive been a happy customer
From stage 2 on Ko3 to now pro tune on F23t wmi its only been fun , car pulls hard , a real eye opener, Aaron did it again i must say tune is on point.

I am really pleased with the tune that Stratified has developed for my car! I have a laundry list of modifications so an "off-the-shelf" tune wouldn't cut it for me. I reached out to Stratified to work with their knowledgable engineers to create a tune specific to my car that not only helps it run great but ensures safe operation as well. Going through the process also helped me learn more about my car and the values to keep an eye on with the accessport, which will continue to pay off long after completing the tune. I WILL be returning to Stratified in the future as I continue to modify an upgrade components of my car. Looking forward to taking it to the track in the near future!

Working with stratified was an absolute pleasure from base file to completed product! The car is making 347whp on a FBO k04. It packs an impressive punch but yet retains 100% of its putting around town drivability. I can’t wait to see what this car has in store for the future while working with stratified! I will be using them for all my tuning from here on out. Thank you and superb job! Couldn’t have asked for a better experience!
