r53 Pulley Reduction
I have an 05 r53 with a 17% sc pulley reduction that was installed by previous owner. Has been throwing lean codes for past few weeks and cannot get to the bottom of it.
Are larger injectors such as 380cc necessary with this size pulley reduction? Any other likely causes of lean code?

And yes, vacuum leaks should be the first thing to look at, our fuel regulators are controlled by vacuum, incorrect vacuum/boost, incorrect fuel delivery to the injectors.
And yes, the ECU does such a good job of controlling things, it doesn't take much to hide a vacuum leak so that it's not really noticeable with the normal rough idle signs.
