Speaking from seeing some Bosch VW pumps in VW's convert from baromatic pressure adjustment to boost enrichment by some guys, some even replaced the top hat with an LDA one and made themselves a turbo pump.

Cannot we do this to the OM606.910 pump, Its got an aneroid device on it that compensates for altitude right in place where the ALDA should be.

Dieselmeken shows outside adjustable ALDA for Mercedes Superpumps - YouTube

My version, there is also possible to change the ADA to ALDA on N/A pumps, however the outside version gives you a chance to adjust it easy.

That is fantastic.
