GTI convert from 2020 model to 2018.

[Rasmus_GTI]

Hi All

I am super disappointed with the sound of my 2020 wltp GTI and want to convert everything to a 2018 model.
Actually its the worst sounding car I ever owned.. But other than that I love the car!
So far I bought a downpipe with 2xcat instead of gpf, and I am planning to buy an ecu from a 2018 model too.

What else has changed?

Thanks!

I think there should be way to hack current ecu to not care about gpf like some dpf car owners did. On gpf car there should be a few sensors for gpf and I believe thats it. You shpuld know in many countries this mod is highly illegal especially in germany
