Title: Boost controlled by KFLDHBN? Me 7.5 Post by: miraimihai15 on July 22, 2024, 01:18:08 PM Hello, I have understand its possible to control the boost pressure only via KFLDHBN and not by LDRXN on 1.8t me7.5
How can I do that? I need to rase the LDRXN? Thanks Title: Re: Boost controlled by KFLDHBN?

I need to rase the LDRXN? Thanks Yes, you can use either to limit boost pressure. By and large, for consistent torque, limiting via LDRXN is usually more common, since limiting via HBN will give inconsistent results depending on conditions (e.g. altitude). |
