charvezding 0 Report post Posted April 26, 2011 (edited) Hi guys Got a mate with a stock standard 2001 E39 525i (M54B25) Looking to get a bit of extra power out of it. What are some of the mods he could do? He Just wants it a bit faster! Cheers Phil Edited April 26, 2011 by Charvez Quote Share this post Link to post Share on other sites
Greg111 13 Report post Posted April 26, 2011 (edited) M54s are pretty good standard, very torquey. Better breathing is always a good start, panel filter, extracters/exhaust system, all depends on his price range really. Edit: This if still avaliable, http://www.bimmersport.co.nz/forums/index....mp;#entry409176 Edited April 26, 2011 by Greg. Quote Share this post Link to post Share on other sites

Gotheschu 1 Report post Posted April 26, 2011 Easiest way to get more power would be to get a proper tune. Gavin @ Hi velocity or Hans @ NZ Performance Tuning.... Quote Share this post Link to post Share on other sites
