: X3 power upgrade

It seems as if the Shark Injector Software is not available for the X3. Do you guys know of any other software that is effective and affordable, that could be combined with a cold air intake?

I've searched this forum and haven't found much. Thanks.

Only thing I know of is Dinan but it's a little pricy. If you put the right combo in you can get about 17-20 extra HP though. And don't believe those CAI adds claiming 20 HP+ :rolleyes: You'd probably be lucky to get even 2 or 3.

One thing about Dinan is that all their mods are dyno tested on the cars they were made for. The HP gains they list are true.

by a diesel X3, you'll see the real power upgrade, minimum 30hp... i know diesel engines doesn't exist in US, unfortunately :(
