The emission stuff is there for a reason, not only user headache. The fact is, once the emission stuff gets deleted the car will stink and smoke and there is no way around it. Could be more, could be less, but it will be nothing like an original car.
I miss my clean car in a way, but everytime i step on the gas the regrets are gone with the smoke in the mirror

Some things maybe different between tuners. I'm aware that both BPC and JR Tuning offer EGR delete with the rest of the emissions systems active (DOC/DPF/SCR in place and on). I personally have such a tune, and they offer multiple EGR options including, a full EGR tune out, or a partial so that the EGR is only active during cold starts and or during DPF regens (not required, but improves fuel efficiency). EGR partially or fully disabled opinion?

Also Lots of folks run EGR blocks with no tunes and have done so successfully for > 60K miles. Hooper on the 335d forums blocked his EGR with no software tune for for more than 60K miles and the car functioned normally (other than an SES every 2nd start until it was erased) Those with the blocked EGR

The X5 does have 2 EGR paths unlike the 335d which makes things a bit more complicated to block.

I'm running a JR Stage 2 Tune with EGR delete and have not had an issue with my DPF becoming sooted up, it still does normal regens, been very happy with the tune.
