I'm sure its been discussed before, but I'd like opinions on the best Chip available for my 1993 525i Touring.

Mark at EAT seems highly favoured on this forum but here in Australia, we also have PowerChip http://www.powerchipgroup.com/produc...=1992&make=BMW showing very similar figures.
Mark will ship to Australia.

There are a number of other chip tuners such as Racing Dynamics and I'm sure a few others.

Its not just a matter of out-and-out HP/Torque increases is it - its also smoothness, the delivery of the extra power, starting and fuel economy as well.

Love some feedback please - especially from any Australian/NZ members, but like to hear from everyone with good or bad experience.
