Mapped today (Dervtech): e90 330D remap, EGR and DPF delete
I've had a quote from a reputable company (dervtech Manchester) to do the above and have been told it will make over 300.
Are there any pro's and cons's of stage 2 over stage 1? I don't wan't any issues come MOT time or dashboard errors. I've been told that in theory it would fail MOT but they've not come across it. I'm in two minds. Thoughts? Last edited by kash330D; 03-30-2019 at 01:45 PM.. |

The DPF removal will result in an MOT fail unless you have a friendly MOT tester....
The MOT guidelines were changed last year to specifically include "DPF Tampering and Removal" and will instafail.... Something to think about. The EGR valve however is not included in that and can be removed with no penalty. As for dash errors etc... As long as the DPF and EGR are mapped out then you won't get errors as far as I'm aware. |

You can make good power when you leave the dpf in place. You do need a decent tuner though, BWChiptune get good reviews on here. I'm sure they will be willing to advise you if you phone them.

Jason is one of the best in the business, just Google BWchiptune and you'll see why. I travelled a long way to get to him but it was well worth it. |

Ahh that explains the extra horses then, so your pre lci gets 305 without DPF? I need to get mine on a dyno as I have no idea how much its putting down. Love the 335D as well absolute beast,, it's the spool from the twin turbo that I really like. My goal once insurance drops is to follow what a chap did on YouTube (bmw power) I think the channel name is, he got 457bhp out of his 330D pre LCI, a lot of work but I've enjoyed working on mine so it would be a good project. How's the 335d in respects of regens and soot (if you do monitor that is)

Mapped today and got these figures.
Apparently there was already a tune file on the car - supposed to be 231 stock. Feels much stronger and does pull more through every gear. I was expecting a little more, but i haven't driven it that much and didn't realise it was already tuned if this is true. Gains seem strong either way? |

ha ha ,,thats honestly what they all say,,the dyno stock runs are over reading,,you can knock 30 bhp offf your final figure,,durham remaps done my 330d had the exact same as yours 252 and said it had a map on it,,nope its because they are knob heads inflating there figures,,my 335d made 280 bhp stock on a proper dyno....

I simply dont understand why if BWChiptune will remap remotedly, you'd even consider going anywhere else. Pulling the DPF off a diesel is so 2009 FFS lol.

Can't believe the OP went against the advice and got the dpf removed. Hope he knows a friendly mot tester and also doesn't get pulled. |
