The system has been pressure tested starting from the y pipe so you say my leak would be at the maf housing itself or at the accordian hose? Because after them it was holding 15 psi just fine.

Then  move on, and just assume you had a bad fuel filter, fpr, or pump before.

If you aren't seeing problems, pull 10% out of KRKTE or MLHFM and call it a day.

Perhaps he has a small boost leak, or a slightly different maf, or a different intake setup.... unless you are seeing significant fueling problems in your logs (or wideband), i'd just stop worrying about it

nyet,

I've did what you suggested and got about 7% off of KRKTE and it did not really make the situation better but in return it made the car shake like crazy with a good amount of misfires and the LTFTs still dropped. I've attached the VCDS log I managed to make and I did another pressure test which came out negative, except for the thing that my PCV valve which connects to the Y pipe is releasing a good amount of air (I guess that is normal because it releases fumes back to the Y pipe under boost?)

Thanks

LTFTs take 50-100 miles to really take effect.

You may need to log STFT at various loads; perhaps there is too much variance.

Also, you should cap the PCV before doing a pressure test.

finally, please dont bother with VCDS, and get me7l working..

fra_w, Frao, and so on. You will see them clustered together in config file.

Well we have basically ruled everything out and I cannot find anything wrong the only thing that pops into my mind is the EVAP system. Euro cars do not have that, but the M box files have code for it,
and the only modification in my M box file for that is just CLALDPE zeroed to to avoid a DTC about it. Do you guys think that more should be done to totally code the EVAP system out, or do you guys think that the EVAP system should not affect fueling at all?
The only other thing that comes into my mind is that the tune I am using has been done for 94 octane fuel, but I am running 100 oct, so i wonder if the pulled timing for the low octane fuel would affect the LTFTs that much. ( I basically have 0 timing retard.

Thanks
