Upgrade the turbo and change to times an overboost

[maik_93]

Hi I have mounted a turbine gtb2565vk instead of the 2260 in my audi a5 3.0 tdi...have any insights on how to act on an overboost? I found too many conflicting opinions and I don't know if I should increase or decrease the values in the map

I can not help, but it would be easier if I did a log with the turbo pressure

No one who is able to help me?

If the turbine is big you'll probably need to lift, try and do the log, and no one will tell you with certainty what to do

The pressure of the turbo drops after 4000 rpm the diagnosis me from 3098 hpa so it should be around 2 bar removed, the atmospheric pressure

Post the map and tell us what you want to achieve, 2 bar at 4000 rpm, it seems to me a good result. You have found the network the graph of the turbine gtb2565vk?
