I recently bought a BMW 320 d (E91) - 2007 touring (163bhp) and I am looking for some good tuning tips. I have found it difficult to find well founded and fact based information on this subject when it comes to the details. Any how here are my thoughts, and I would be very grateful for knowledgeable and well founded feedback:
Thanks in advance.
- Original thought is to install a K&N filter to increase breathing and to slap on a diesel-box/tuning-box/piggy back (the one you love have many names) since turbo diesels normally are rather power responsive to fuel increases. However, most seem to treat this type of solution as something the cat brought in….I do not know if this view is well founded or just experiences form people who did not understand not overdo the fuelling.
- Alternative thought is to buy a DIY package for ECU flashing offered by many tuning companies (including flash device and tuned map). Advantage is that you do not need to go to service station when you want to flash back to original. Disadvantage is that it is significantly more expensive than option one and you still do not know the quality of the map you upload (too many posts shows that even the more renowned brands seems to make them selves unavailable when the S__t hits the fan and the car doesn’t work properly after remapping )
- Last option is to buy an unlooked flash device, download a free/demo tuning software and do it the hardcore way yourself by comparing the original file with tuned files available on the internet and trying to understand the logic. (I will likely offend some one now but I say it any way, it cant be rocket science judging by the people making a living of this in my home town…enough said)
Thanks in advance.
