I have been interested in a software upgrade, but wanted to try something other than the JB3 or JB4, everyone else in New Jersey already has that on their N54. I saw on the Active Autowerke website, that they have a handheld programmer like the Cobb. The noticeable difference off the start is...
-GRUPPE M ram air intake
Product number is FRI-0323. It is for BMW 135i (N54).
-Active Autowerke Processor
for 135,335,535i and xi models n54
-Standback 2 direct injection engine...
