Fiat Stilo 1.9JTD 115HP EDC15C7 - target boost issue

Hi,

I am used to EDC15P VW tunes, and I have some serious trouble here with a fiat Stilo 1.9JTD.
I did a basic remap without extend axis etc. Its all fine till 3000rpm but above the target boost suddenly drops to 2110mbar.
Dont know why. When driving with stock file and just add 90mbar its all fine.

Stock

Stock with more boost
+ boost limiters, + vnt maps -> working! nice boost till 4500rpm

Tuning - >
all axis are stock, basic tune with 310Nm / 140HP

I would even pay for getting it fixed. Its annoying :(

greatings and thx for your time

You began tuning without enough basic knowledge. You hear some about SVBL?
And keep in mind that you jtd is EDC15C CR injection but you study tune with EDC15P that is PD injection and not the same.
This site have good examples for you study:

SVBL (abs) = 2500mbar
SVBL (rel) = 1500mbar

I think I do not need to edit it for my target boost. You said, that I have not engough knowledge.
Nobody has enough knowledge... That is why I am here to ask. :D

Any hint you can give? How would you set SVBL for my boost target?

after 3rd VNT map there is sth like another SVBL. Changed it from 1980 to 2500 but issue still remains.
I just dont get it... There are lot of EDC15C7 Files out there, but I just do not find the mistake in my map :(
