Highly affordable mods that improve power
I follow all threads on this site, especially those that relate to power increases or perceived power increases (3.91 diff). It appears that there is concensus that one or two very affordable mods should be considered:
1. BMC filters instead of K&N or OEM. Filters appear to cost $182.
2. The device recently discussed that has MB e55 owners confirming its benefits in modifying the 'drive-by-wire' to make it more responsive. This is the device manufactured in Greece. Seems to cost $270 (P.S. no one has yet tried it on the e60 M5)
3. The 3.91 diff that seems to improve (seat of the pants) acceleration and torque. (This probably does not fall into the category of "highly affordable.")
