So I done did it.

Absolutely worth it.

Insane gains. The dyno before the tune was at 170hp at the wheels don't know what that is corrected to engine bhp because he didn't print/save that graph . Anyway, after the tune I came out to 277bhp (corrected to engine). Keep in mind this is a car from 2012, which BMW gave 218bhp on paper. AND I did NOT change the intake at all.

So this 325i basically just became a 330i, damn. So happy.

What's up with the end of that curve? Did the dyno lose the pickup for RPM, wheel slip or something?

I think he cut it off too early, no clue why. I don't really understand how these things work.

When test driving it runs smooth over all 7000rpms

The RWHP looks about right for a tune without the 3IM. 212 that's about 10-15 less then the average N52 with a tune with 3IM.

Don't really think much of the crankshaft HP values. Correction factors seem generous.

Also the dyno shop should rerun your car. Data is really messed up and not really reliable.

yeah, my 330i put down about 215-220whp with the stock tune.

If that's 212whp, it's pretty good compared to your baseline! - but it's not 277hp, lol, not even close. you aren't losing 65hp on these cars to drivetrain losses. But you should still be happy

So at the end you done only the tune in NL? not installed the 3 stages manifold and have it tuned for it?

Correct I did only software and the difference was still insanely good. N53 owners are super lucky with their possibilities.
