Does the 3.6 fuel economy improve with egr delet

Marginally I’d say but ask Alive or BAS 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
New Defender D300 90 on order so "Rory" will be going to a new home....!
1974 Series 3 Lightweight = "Millie"

Can't say I noticed any difference. 2016 Skoda Octavia VRS Estate
<gone>2009 FF Vogue TDV8 Buckingham Blue</gone>
<gone>2015 BMW 520D SE (not my favourite car)</gone>
<gone>2009 D3 HSE Galway Green</gone>

Range Rover and fuel economy is not a discussion point tbh  2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Blank and remap the EGR's out to save the turbo's from eating them although this does not prevent the turbo's eating themselves for no apparent reason....
More power and quicker throttle response are the other benefits of a remap. As for economy - it will be worse if you can now accelerate faster  2012 TDV8 Vogue (L322)

I’ve not noticed any difference in mine 2007 TDV8 Vogue SE
2005 BMW E63 645ci
2009 5.0 Supercharged autobiography
2024 Porsche Macan

There's no reason fuel economy should improve UNLESS you had a very faulty EGR before delete & then economy should only "improve" to what it was before the EGR deteriorated.
PS It didn't on mine either  Paul,
