Tuner recommend N51 328i

Hello
328xi 2009
This version already has the 3 stage intake, it is 230hp.
I would like to know without starting a war.
If you can recommend a tuner?
I also saw that Bimmerlabs is free but I can't find much more information on whether it improves something or doesn't improve anything.

In the forum I have seen that stagefp and 22rpd are highly recommended.
But I would like to know your opinion.

Very very thanks

Bimmerlabs tune is free and as far i know makes an N52 with stage 3im output like 260 crank, not sure for n51.

Stage fp and 22rpd are both great tuners, personally have 22RPDs tune and I love it.

You could always contact either one and see what you could expect with from a tune on your current set up.

Can also recommend the Kassel tune -- they did mine when I swapped to the 3SIM. Tune is absolutely seamless to stock and the power gain is substantial (201 -> 225whp dyno'd before/after).
