Major Torque loss - Need Help Figuring whats wrong

Hey there mk6'ers I really need some help.

I have a 2012 mk6 GTI which Ive had for a year and have had zero problems up until now

Around a month ago my car lost a lot of torque, thinking that it was just the fuel I went through a couple tanks and ran some fuel cleaner through the system to try to help. I also replaced the fuel filter itself, yet none of this helped.

After dealing with this for quite some time I took it to a european specialist to find out what is really going on. With some time with the car, the mechanic there told me that there is a issue but he's not exactly sure what it is. Come to find out, the car that I bought is tuned with a tune I have no idea what is (They checked for giac and APR and it is neither) and there is an issue with the timing. In his words: the timing is too fast for what it should be but nothing is showing why. A possible fix in his words were either a reflash with the tune (but I'm unsure with what tune it has) or something mechanical possibly the catalytic converter being worn out. Asides from those two ideas he said that you could pretty much start replacing parts and never stop. The mechanic recommended me to keep driving the car just not at full throttle to hopefully reveal a code. There are no codes on the computer not even soft codes checked with a VAG com. I think this is a decent idea but I already put around 2k on the car with the same performance lack I do not believe that it has gotten any worse and definitely not any better for that matter.

I replaced spark plugs 6k ago along with a full service of the DSG. I always use 93 octane fuel and never kill the car. I'm really here to find an answer or possible ideas from people here that might have had the same issue as me. Thank you all very much for your time.

I'm sure a dealer could flash it back to stock and that would help confirm/eliminate the tune as being the culprit. Then you'd be on your own if you wanted to put another tune on it since you can't find what tune it currently has. However, even if you could find out the current tune, I'm not sure you'd want it since it is allegedly causing the issue... good luck:thumbsup:
