Thanx Rob, which part is that and what does it do?

It's called turbo whine, and yes it will be louder now.

Cool that doesn't bother me much I just want my Power Back. What's the correct way forward?

Remove the other emissions systems relating to the DPF and have them tuned out of the ECU. Others will chime in on a list of those systems as I currently run an intact emissions system on the wife's x35d.

Edit: Actually it may be helpful for you to read the threads of members here who have deleted the emissions gear. There are at least 2 or 3 pretty complete delete threads.

You clarified the center box was gutted, so he did it.
Sorry I meant scr... Didn't notice scd till now

(which assumes all your issues are fixed...there is no other problem...and it is just an emissions thing. I dont recall 'not having tuned out the emissions causes low power' as a known issue. DUnno)

Well according to Plug&Play site apparently that's the case, I'm taking it in for tuning shortly I'll give feedback what these Pros say lol!

'pros'...lol indeed.


good luck

Thought I'd share this with other people with a similar problem: DPF Removal
