Nanocom data - overfueling!! ???

Long story. Failed MOT with 7.5 emissions value (3.0 is max!)
TD5 Alive Tuning (stage two?) w. EGR blank, larger intercooler, remap.
I knew it's been smoking too much lately .. but 7.5??

I had a leak at the EGR blanking unit which I sealed yesterday. I also cleaned out the inlet manifold for mug.

When hitting 4000 rpm after the cleaning/sealing the engine cut off with a big black smoke-trail on the highway. It did not completely stall but cut down a second or so. Limp mode I guess.

(I once earlier tried this cut-out and at that point one of the jubilee clips on the intercooler hoses had failed - escaping the turbo pressure.)

Thought the MAP was mug'd - so cleaned it.

New test - felt it was running a little rough. It never really repped in a nice way. Always a little rough and with a feeling of some resistance. Disconnected the MAp and wow! The rpm went up so smooth!!! and of course I could also easily hit 5000 rpm if I wanted. Nu rough running - no resistance at all. No smoke but of course also gutless.

Connected the MAP again and recorded a Nanocom file. 4000 rpm - limp mode again. Three pictures attached representing the Nanocom data at the time of going into limp mode.

If I am wrong - please correct me on this view:
1) The MAP values look ok?
2) The MAF values looks ok?

The injector balances are all within +/-8

Why am I experiencing a 7.5 emissions value at the MOT? ... and why do I go into limp-mode WITHOUT any overboost fault readings???

The fault readings are: 10-1,10-3,10-4,10-5,14-1,14-4,14-5,20-5
01-07,01-05,04-01,14-03 (I believe 04-01 is related to disconnecting the MAP)

PM and you can get the Nanocom recorded file

Thank you all!

Bump

My injector balances are within +/-2 on all cylinders.
Are you sure the MAF is good?
What Nanocom are you using Nano1 or Evo?
Send me the Nano files and I'll send you mine to compare. I've PM'd you my email.
I've found some overboost errors are not recorded and disappear when you cycle the ignition. Catch the ECU errors to file before you turn the ignition off.

Dear Shifty! Thank you for offering your support! I've been on the road a few days and things have actually solved. I had no fault-codes on overboost - also not when not turning of the ignition. I decided to shorten the wastegate rod by a full turn, replaced the air filter (again), gave it a big dose of diesel-aditive .. and beat the sh*t out of the engine. I really gave it a lesson ) .. and it helped. I went to the MOT in a different city and the values where measured between 2,58-2,70 .. perfect!

However i would very much like to see one of your Nanocom files .. or a few.
I will record a new one on mine too - and share too. Maybe we can learn something anyway.
Please be patient with me time wise - you will get it latest by tomorrow...
