I've seen a number of posts relating to EGR delete, remap and fitting a turbo drain. I'm in the process of buying a 3.6 TDV8 (2009 facelift with digital dish etc) so just wondering why these mods are done in terms of benefits i.e. Does it save the turbos?? Also what sort of costs would the mods incur? Any info appreciated.

EGR removal/deletion is very common on the 2.7 V6, not seen so much on the 3.0ltr.
From reading on here, it looks like it's not recommended for the 3.6 V8. Obviously not my personal experience as I've only had the two former; blanked them on my 2.7, no problems so far on my 3.0ltr ( , done it now).

I have the TDV8 , my indie advised against the EGR delete when I asked him about it so took his advice.

EGR blank and delete on the 3.6 TDV8 is a common mod.

RRS TDV8 EGR delete isn't that common, I think. It requires a map change too so it's not a simple DIY job like on the 2.7TDV6.

Not sure there's much benefit to be had from doing it on the TDV8 as the EGR seems to be much less problematic than on the V6s. Certainly, in my experience they'll go 150k miles. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
