Hi!
Here is my problem - I can't make boost more than 1750 mBar after 2500 RPM.

I changed only 3 boost maps LDRXN, KFLDHBN, KFMLDMX. Though I didn't change KFMIRL, KFMIOP, KFTARX etc.
Could anyone explain me how to make boost around 2000 mBar?

I think I have to change KFMIRL and KFMIOP cause it has only 75% torque request. Am I right?

No, he won't. His KFMIRL already requests close to 200 load which will be more than 2000mbar boost.

Thank you for reply.

I tuned some Audi A4 1.8t and I changed only LDRXN, KFLHDBN, KFDLULS, KFMLDMX and everything was perfect - 2000 mBar.

But that's a different story with Passat...

Could anyone tell me, which exactly map(s) must be changed for 2000mBar?

Is it requesting 2000mbar boost?

Log rlmx_w, rlmax_w, and rlsol_w

That will show you (us) where is it being limited.

Specified load without correction

Specified load after  correction

Actual load

I would suggest using ME7L or at least ECUx.

If using VCDS, you would need to include block 213 to get rlsol_w.

Is it really that hard to find and change 2 maps which are pretty well described over this forum?
