Hi Sparco!
Little question i have a C2 1.6hdi i want change the stock turbo and much people tell's that turbo of the C5 2.7 hdi is good for my engine ,what you think?

Thank you

You could try that one, tho I dont know which one is used on that engine...
I would recommand a GT17 series turbocharger... it seems the gt1752v is the best option, as the gt1756v might produce more power, but with bigger lag...

Hey,

Where can the air mass meter calibration?

I'll have look at your file in the weekend ;)
You have a new maf to be installed?
This one maxes out at around 1100mg/stroke

Here in the temperature around 0 degrees.

+ 2 bar of boost pressure. So 1400mg / stroke the air mass, but from 4000 to 5000 rpm, only 1000mg / stroke.

A few days ago I was in a Toledo TDI and after air mass meter replacement was good.

My problem is that I could not solve. The amount injected 85mg / stroke, but only up to speed 60mg and I do not know why.

What do yoe mean by that?

Off course...
Volumetric efficiency drops as revs rise...

are you sure the turbo is keeping target boost?
Do you have diagbox or lexia to make proper logs?
