Highly recommend an EGR delete, it does so much good for the engine. Been running mine in my 335d F30 and all of my previous cars. Even with DPF intact, the regens are less frequent due to less soot build up.
The only problem is finding a guy that you can trust. To code it out fully its not easy, as most so called tuners only blank then them or unplug them and then just delete the associated DTC's and the job is done.. But thats not the proper way.
