Since I fitted some Alfa DSLA144P1295+'s to my car I have been suffering from far slower turbo spool, so today I decided to make some quick logs.
..and by the looks of it I need to adjust the actuator - or find out why it makes so late boost with the bigger injectors.
First, a log of the injected amount:

The Turbo pressure + MAF reading

and finally the VNT % and inlet temps measured in the MAF:

..and the whole data:

I wonder why the turbo makes so late boost with the bigger injectors, I have retarded the injection quite a bit on it by now - but it does not make a huge difference. Before I sued ot have 2.5bar (absolute) at 2.000, now I have 1.8
Looks like I have to take a look at the actuator, I don't think it can pull the vnt fully.
What do you think? As for power, do you have any "guestimates" on this?
