bpv, typo. Not much left, especially w/o logs.

possibly collapsed inlet, clogged cats, etc.

Bpv haha okok

Well, a collapsing inlet is one of my thougts, but can it cause timing retardations and become better without maf?

Can he make proper logs with vcds or he needs me7logher? In this last case, impossible.

Ps: He's got a tube instead of cat

I'm not going to bother guessing anything else; it's an utter waste of time.

What do you consider a "proper log"? What variables?

Tell him to visit a local shop and let them sort out the HW since he is not able to do it himself.

1 - MAF readings are to much lower than expect

2 - Lambda is too much rich than expect

3 - Pressure is too much lower than expect

All this indicating an air leak from MAF to turbo, consider verifying DV is not leaking, and all one direction valves under manifold and next TBI.

But as said before without more detailing logs is hard to know...

Half-fixed.

The back muffler was clogged. He put a sport one and now it pulls ok. Maf and boost readings are ok but lambdas keep higher than spected.

Maybe the lambda sensor has suffered because of the pressure accumulated in the exhaust and its bad. If we fix it, I'll post the solution. And again, just to make it better in the future: What do you consider a good log? What variables in this case? I assume using me7logger and not vcds..

me7logger, log attached as text format and perhaps optional screenshot from ecuplotx
Variables/memory positions depending on what the symptoms are

And the cat is now clogged because of all of this extra fuel?

No problems with the cat adam, he had a tube instead of it.

Stock:
Catalytic converter, resonator, muffler
Tuned before:
Tube, resonator, muffler
Tuned now:
Tube, resonator, sport muffler

It seems resonator is ok, as he tired first of all by unplugguing the exhaust from the Down pipe, and results are the same as now.
