yep, i blanked off a egr on a corsa b 1.2 16v the other day. Blank came from a polish guy for that too as it happens. Not spoken to the owner yet to ask if it made noticeable difference but if forums are to be believed they go noticeably better. She has constant eml on that though cause it don't work, causes the tb to clog up eventually. car ain't worth anything so thought we'd try one of these blanks to stop tb clogging.
contemplating dpf removal and egr blank on my alfa atm. Just cause dpf's are a silly invention but the egr apparently clogs on them without the dpf.
