DW 3D.JPG

Hi mate,
you left untouched some maps,
Turbo limiter/temp-74AD2 size 5x5
TL 7A93A 19X1
TL 7A98A 19X1
TL 7A9D4 16X1
IQlimit 7B0A6 8X8

Anyway, must rework your mod file, is not the best can get, look only on DW map in 3D and you will see!!!!

M57D25 with GT2556V is, at least with automatic gearbox, quite some work to get it right. You have to lower the boost quite a lot over the whole map except full throttle and rewrite the VTG map from scratch to get faster spooling in every rev range.

I did that a year ago: http://www.motor-talk.de/blogs/tommys-b ... 07655.html

Calibrating the VGT will be a huge pain with that turbo. Not possible without logs. I have made 320d 150hp with GT2260 and it was a hard work for 1 week non-stop calibrating. Looking at the logs seems beautiful and looking at the N75 maps seems nonsence but the car was runnig hell fine.
