Boost pressure

[Shotgun]

Hi all, I'm about to install a boost gauge after my re-map.can anyone tell me the standard boost pressure for a 2010 e70 x5m? And maybe roughly what pressure should be after the autowerx map? Many thanks, cheers.shotgun.

You might find something in newtis, but most likely it will be a set value in the BMW Diagnostics software. Not many X5M owners in here and I’ve never seen mention of an Autowerx remap. Can’t they tell you themselves?

Id think the boost won't have changed much if any , more power is got by putting in more fuel mostly. Must be a proper beast now though

610 bhp now. 15mpg. Was 11 before the map.cheers.

Sounds like a lot

555bhp as standard,610 after the map. The boost pressure is turned up which is why I'm asking what the standard boost is. I will ring the mapper on monday.

I was thinking after and your right for petrols the boost is raised as they need to run at a certain air/fuel ratio but for diesels they mostly just get the fuel pressure turned up
