Audi A6 1.9TDI AFN+VNT20+0.216nozzles

Hi peeps, I got my kinda project car(Stage 2) remapped a couple of years ago, but I think there's something wrong with the map, esp. with the turbo maps. Since I don't have original file, posting just tuned map. Pros, what do you think?

It's the Audi A6 2001. on manual 6-gearbox with an old AFN swapped instead of 2.5TDI V6, with VP37 pump(stock 10mm plunger).

It has some hardware changes, like:
-VNT20 turbo(it's the turbo from 2.5TDI V6)
-0.216 nozzles(from 2.5TDI R5 VW Transporter)
-3 bar MAP
-2.5 TDI V6 Intercooler
-Koni sport air filter, since I can't fit the standard air filter box anymore, bc of VNT20
-EGR is OFF, even physically
-MAF OFF

The prob is I got some turbo spikes on diag. logs. Got new N75, but after fitting new N75 the engine started to choke(like working on 3 cylinders) till ~3k RPM on 1st and 2nd gears, but once it gets to around ~3k, it pulls out like a bullet.
Hammered it to ~3,5 mg/stroke fueling on idle.

Any ideas?

OK, I found original file for this ECU on the internet and compared them both.
I'm not a pro, but N75 duty cycle map seems to be badly modified. It could be a reason for overboosting at low revs and turbo spikes?!

Any suggestions/opinions?

Attaching the original file

:shock: Holy F**K, full mg fuel from 1000-4200, are you nut?

N75 very bad
SM very bad
DW bad
EGR not touch

Good parts setup for the car :thumbup: , but your tune is very very VERY bad :thumbdown:
You need to learn more and don't drive at that tune for now.

Thanks for your answer!
well, this is PAID remap to be honest :D :D
I'm just starting to learn remapping and I don't even have another map for now :roll: got the car with this remap lol.
Should I use original map, but just map EGR and MAF out, since I don't even have them physically? :oops:

Thanks God I purchased the cable to check existing map lol. So should I just use original map, but remove MAF and EGR for now? I don't have them installed on the car..

Oh, forgot to attach it.

Hi peeps!
Made some corrections to the maps. Is it better now?

P.S. Anybody have DAMOS file for my ECU? Can't recognize some maps and can't find the IQ by MAP map.
What are these maps, which are already edited?
What address is for IQ by MAF and IQ by MAP switch?

2D 0005A00A DD7C
2D 0005A05E DD7C
2D 0005AE7C DD7C
3D 0005CD50 DD7C DAB4
3D 0006168A DD7C DC7E - looks like EGR
