If I'm hearing it correctly, there is nothing to be gained through ECU tuning on a non-forced induction engine (skip to 6:25). |
That's correct for most NA engines (including the previous gen M54). But with the N51, you can take advantage of the 3 stage intake and the valvetronic to make some more power. With the N52, you can put the 3 stage intake on and make a very large gain with a tune.
