What tunerssay about us
We have been using the YASTUNING portal for years. Without a doubt, they are the best company in this business. The support is the best in the world, super fast and always on point.
We ran into some issues after a complex DPF and EGR delete. We contacted their team and the support was incredibly fast. They adjusted the file in minutes, and now everything works perfectly. Top-tier service.
Ordered a Stage 2 with a pop and bang add-on. It was done super fast, and it sounds absolutely insane. It is loud and aggressive, exactly what the customer wanted. He loves the tuning!
Their file service platform is incredibly easy to use. Uploading reads and getting the modified files back is seamless. It saves our shop so much time on busy days.
I am not a professional shop, just a car enthusiast. I requested a custom tune for my daily driver and the process was straightforward. The car feels completely different and so much faster.
As a workshop, we need files fast, and YASTUNING delivers every time. Stage 1 and Stage 2 files always run clean and produce great power.
We run a busy shop and use their automated web portal every day. The WinOLS integration makes managing files incredibly fast. You just upload the read and get a perfect file back. Best company out there.
We were stuck on a 3.0 TDI with complicated DPF and EGR issues. Sent the file to YAS, and they fixed it in 10 minutes. The car runs flawlessly now. Literally the best support in the world.
A customer wanted a Stage 2 with a really loud, aggressive pop and bang. The file came back super fast and the car sounds crazy. The customer loves it. Fastest service I have worked with.
Absolutely the best tuning files we have tested. Support is blazingly fast, and the cars always leave our shop running perfectly. 10/10 company.
