After years of experience within chiptuning business as senior ECU calibrator at one of the biggest VAG tuners worldwide, I decided to start my own business and was looking for a professional partner / WinOLS reseller who offers high quality tunes which I can use as a base file.

Mayk from filedatabase.eu was the first company responding to my request and happy to help. Their personal customer service directly by Whatsapp is amazing for a B2B file service. No matter the question, Mayk was able to answer really 24/7. Even within the first month in which I was still looking for a reliable partner and didn’t purchased any software credits yet. They exceeded all my expectations.

Currently the customer service is still as amazing as it was first so I can’t give any bad word about this and only recommend it to everyone.

Most of their files are dyno measured as well and these numbers are included in the file name. For me as experienced ECU calibrator the quality of the files isn’t the most important, because I will always analyse them all myself before flashing. However, even for unexperienced tuners I can say that even their tunes work perfect and are of proper quality. No simple and incorrect (or manipulated) modifications which I saw a lot in the past at competitors, but true tuning files that still consists ECU factory functioning and safety functions.

In addition filedatabase.eu is one of the best priced big WinOLS resellers as far as I know. I actually didn’t find a cheaper one.

All in all I am super satisfied and can recommend filedatabase.eu to anyone. Keep this up guys!

Leidenschaft statt Berufung!
Hier sitzt das Herz am rechten Fleck. Super Beratung und blitzschneller Support. Man merkt deutlich das hier der Kunde König ist. Völlig abseits vom Mainstream Tuning geht man hier noch speziell auf Kundenwünsche ein. Ich bin mehr als HAPPY. Mein RS3 8V ist ne Rakete geworden. Ein völlig anderes Auto! Danke für ALLES Mayk!
Mit gutem Gewissen werde ich Dich weiterempfehlen.

Guten Rutsch & bis demnächst!

Habe schon mehrere Anbieter getestet, von zu hoher Abgastemperatur bis zum ruckeln. Ich muss sagen, Mayk und sein Team macht TOP ARBEIT und hat auch immer ein Ohr offen, was mir sehr viel bedeutet. Support einfach wie man es sich wünscht !!! Top Files, alle geloggt.
