Hi folks!

I would like to tune my new (5000km) Cupra Leon ST VZ 333 with Extreme package (akebono brakes, cup seats).
What are my options? I would like to keep the car kinda reliable, it is still my family's daily driver :)
I watched many Golf R related tune videos on YT, so even 545 HP is not impossible for this engine, but I am afraid that would be on the risky side. 490ish is fine for me :ROFLMAO:

APR? TVS? RacingLine? I definitely won't do a "friends and I in the garage over the weekend" tune, but I want a "here is my car, let me know when you are finished" tune.
Sadly I don't have too much confidence in Hungarian tune stops, so I am willing to drive to mid/west Europe to do it at a professional service company with good reputation.

The only sensible option at the moment is the Racingline tuning box I think. It’s £750 sterling I think. But when they unlock the ecu and a map is done you get the upgrade free. I would think that tvs engineering in Holland will be the first to map the box !!
I’m looking at getting one in a few months. Don’t know anyone yet that’s got in on the cupra st yet.
I did see a post on unitronix in the states about there being something in the pipeline tho. Not sure how long or where
