I have some questions:

Really a dirty maf can make my car "cracking" noise (detonation) when blipping in neutral or downshifting? I will clean it tomorrow and see what happen.

The car of the video is a supercharged one, my is absolutly standar and only 8000 miles. Its a 7000 rpm car engine design, and i have reached that peak very often on overtaking or fast acelerations, like with my former dohc-vtec Honda (never an issue with it, excelent car).... But with a really good care.

I agree that this engine is full of noises, almost normal in a boxer layout (this is my 4th subbie, all NA), but knocking on blipping throttle is to much for me in a new car (expensive one in my country).... That why i'm pretty sad.

Saludos!!!

When you clean make sure you use the appropriate cleaner like CRC maf and throttle body cleaner.

Also I really hope it's not the DI popping issue:

That happened in the past when I first started on the forum when people had to replace the seals under warranty which to do yourself is pretty invasive:

It also would apparently get exacerbated by forced induction which is sounds like you have a supercharger.
