2014 328d Tune and MPG question
I have a 2014 328d with close to 250,000 miles on it. About 100k miles ago I did an exhaust change with DPF delete along with a stage 3+ tune.
I am wondering if there is a tune just for the dpf delete that will also just beef up mpgs some more. I average a little over 42mpgs between city and highway driving. I see people averaging 50 and 60mpg and wondering if I'm doing something wrong? I drive pretty conservatively. Side note, there is no emissions testing where I live. |

The cheapest tune is found in your right foot; slow down, coast more, use eco-mode whenever possible, look farther ahead to anticipate traffic conditions, etc.

OP...reach out to whoever sold you the stage 3, they can handle a stage 0 w/dpf delete, you just may have to pay for it and probably not worth the fuel savings. |

Don’t forget that British mpg is not US mpg. British gallons are larger ergo more miles.
Edit: Someone in another thread calculated up UK mpg 57 is us mpg 47. So you are exactly in line with the ones you say get 50+. I used to get 43 hwy with out work, 49.8bestever freeway really trying and keeping speeds down eco pro etc. usually was about 48-49. then I lowered it to the 1.5” limit for funsies, so the additional mechanical drag from the CV joints and aero drag from nose down rake (higher cd) means I lost a few mpg freeway, not much diff city. I can still get 40 ish easy and 47 working at it, but not 50 US!

For reference, my standard UK 2015 N47 320d M-Sport Touring auto (same car as the US 328d I believe) is showing an overall 47.5 UK mpg (equivalent to 40 US MPG) over the last 10k miles.
But I've never been known for having a light right foot |

Okay I’m looking at completely deleting my 2014 328d. So my question to everyone is what do I do after deleting it? Obviously it has to be tuned, but by a professional tuner or can I do it myself?
Any advice about anything with my new car would be greatly appreciated! Also I don’t know how to make a post, so I guess this is a reply?😂 |
