I was thinking about trying to source a 325i tune from somewhere. The power difference between N52b25 323i and 325i is 30kw (40hp). The engine and internals are identical, so a good gain to be had from a tune. Could be a tough ask though as the N52b25 is not as common as the b30. Was going to try flashing a 325i into it with winkfp. I'm pretty sure it's not as easy as doing that though. Any suggestions anybody??

If you have access to the file, it is as easy as flashing it with winkfp
