Hello I Have a performance problem on my car over 2 years. Im a bit desesperate 
Also have this problem in my previous setup stage 2 k03s

mods on the car are:

-Gonzo stage 3 turbo kit and tune
-Evoms Fmic
-New forge 007p DV
-Downpipe GHL 3'' / catback 2.5''
-N249 Delete (I will undelete this mods, I don't think was a good idea)


I don't have CEL but when I scan I have many time this : knock sensor G61 low signal, intermitent.

I don't have any vacc/boost leak. I think I boostleak tested my car over 5 time this summer 

when the car have not all the power (90% of the time), I can feel small hesitation, idle rough, less power in high revolution, less wheel spin in first gear and bad quarter miles. like 15.00, 14.8, 14.6, 14.5.

But one time in quarter mile run, I felt the car pull very better! easy to rev! 13.9 at 102mph

another MAF, N75, IAT, MAP, FPR 3bar, was tested and nothing in this list was faultly.

I can do data logging, graph, but I can't post anything about the .bin flash.

Thank for your help guys and sorry for my english...

I tried for the first time to log with ME7 logger GUI and Visual ME7 logger and I got some error 

someone can take a look to my logz ?

ok !

you think its not hardware releated problem ?

I will try to email my tuner guys, about wgdc and pid

it can be tuned with logz sheet ?

thank you

ho thank for your reply gonzo!. Sorry I forgot to tell you about this code 

I will check my knock sensor and wiring !

many thanks

This maybe help you

From s4wiki:

" If you do scale your MAF, you may throw a "MAF too high" code. You'll have to increase:
KFMLDMX - HFM threshhold for B_maxflr diagnosis
MLMAX - maximum airflow"
