50i Performance Mods???
Does anyonw know if there are any performance mods for the 50i engine? What is BMW's "N#" for this motor? I hear talk about the N54, N55, etc motors but not sure which one they are relating to. Are there any downpipe bolt-on's? computer tuning? performance exhaust? Do I have to worry about back pressure/scavenging if i custom build a Magnaflow setup? Does the computer act funny if anything like that is changed? thanks in advance

The engine code is n63. It hasn't been around long enough in the 5 or x5 to have a strong tuner support base yet, but its growing by the day. I would expect shiv to have a tune in 12-18 mos.
Free breathing helps the BMW turbo engine on both intake and exhaust. I ran a DCI on my n54 e90 with great success, in addition to the proceed. Better dp's and exhaust systems added further to the hp gains. The BMW turbos are managed by a waste gate system, and it improves with a free flowing exhaust.

Dinan has been shown to be horribly over-priced and they way under-deliver.

If you want to keep the warranty and have 500hp Dinan is the route to go. They have the X5 50i package on their new web site now. I have a Dinan tune and like it as well as their service which has been great so far.
With any other tune you take your chances ... I wouldn't do that.
