Hi everyone, just been doing a bit of reading and it seems there is no "Diesel Tuning" Info. Nothing like the stage 1, 2, 3 etc with a petrol. So I thought I would perhaps start one, with a view for people to add information to help those wanting to tune a BMW diesel. Comments are based on my limited experience and knowledge.
EGR - there are some that claim it makes a difference and both arguments for and against. However the general concession is, for a free mod, get it plugged and taped up, your engine will run better without the extra crap
Tyre Pressures - make a difference...
Oil and Coolant - also make a difference, ensure that you use decent stuff and levels are correct
Ok, onto the more serious stuff...
Air Filter - ? (some say it makes a difference, others don't)
Remap - massive difference and really worth doing
Decat - Not done this yet personally, however on a turbo engine allowing more flow can only be a good thing
FMIC or Front Mount Intercooler for those who didn't know the acronym
Performance Exhaust - Haven't put this with a decat as essentially although parts are similar, they are two different items
If there is anything else people can think of in the above price bracket that is easily do-able like the above please add... otherwise I think you're on to more serious stuff...
Nitrous (unsure if this is possible on a Diesel)
Please note for the above, I haven't bothered with other parts like suspension, brakes etc, which are all worthwhile doing if you plan on tuning your car
