: New owner of a 93 525ia, should have found a 535, oh well. Which aftermarket performance chip(s)is(are) most reliable for the 525??? Are the performance claims believable? Is tweaking an automatic even worth it?
I just chipped a '95 525ia, does add some zip but a lot of the zap is robbed by the automatic. Is smoother though on acceleration and the faster you go the greater the additional power (think 20HP more at 5000rpm or something like that).
