golf 5 1.9tdi boost problem

Postby kevin1996 » Mon Oct 09, 2023 8:39 am

hi,

can someone check logs and tell me why i have overboost from 2-3k rpm and underboost after 3k rpm.
I have soft stage 1 260nm 118hp (oem 210nm 90hp) with untouched boost maps (there was no need to raise these values to gain this power)

No limp mode, I think this must be hardware problem not a tune. What you guys think, what would be the problem?

Here the problem may be in the turbo or turbo control (n75), or too low vacuum on the valve.

Did you remap the boost actuator map?

Does it work with original map, or do you still have a deviation?
