Hello, the turbo has fitted 2 weeks ago, its running fine and has good spool up and good power. But everything can be better with a good tune.

So i need some tips because i think the VE is kinda low in boost

Tune and datalog are in the zip file

What do you mean VE is low in boost? Looking at the log you hold ~11.5-11.9 AFR at ~160kPa which is ok. Besides the occasional lean tip-in (tune your accel enrichments) there isn't a whole lot wrong with it.

Only thing that seems off is there's only a 10-15 point spread in the VE table between idle and 7k rpm/160kPa. (which is probably what you meant)

 

Ah thx i will take a look at my AE.

I was confused with the VE and thought that with boost they will go over 100.

 

The VE table will be a lot flatter if incorporate AFR is activated, which you do have activated in your tune.
