Thanks for the replies!

Just a couple of questions, I'm dumb and not very mechanically inclined

@steve99
Yes the car is tuned in a hybrid speed density using MAF on low rpms, or at least that is what my tuner told me.

Low pressure pump is the one in the tank right? By top end do you mean? My problem seems to be at the top end, over 5,5k rpms. By more do you mean that the problem should be more accentuated?

I need to check for exhaust leaks in the headers right? The rest of the exhaust system should not interfere or not?

By DI computer do you mean the injector "ECU" correct? I have to check if everything is connected or?
I don't have the knowledge/tools to disassemble and bench test the computer. If it's a cpu problem my only option is to replace it, but i want to keep it as my last option...

@Irace86.2.0
Yeah i am a little concearned because as you say, it seems really lean. I'm also trying to understand how this things work..

A faulty DI Injector can cause this problems? I have a friend who just changed one because the seal broke, but his car had a CEL and was making popping sounds.

First thing i'll check for leaks and clean the MAF to see if anything changes, but usually i'm not that lucky.
