Hello, everybody,
I am proud owner of a 330 Touring with N52 engine.
Is not comparable to my other two BMWs but for the daily family trips OKay

As with my other BMWs I would like to optimize my performance and have already registered at bimmerlabs.com because I have read here only very good and positive thinks.

Unfortunately I don't get any feedback on my requests

Maybe there are other possibilities for me to find a good and serious tuner.
Like the possibility to flash the files myself as bimmerlabs provide.

i am looking forward to an answer

Grüße
Marco

I like to show the topic here again because would like to know if bimmerlabs still alive for custom tune?

Create a Projekt and Write some Massages over the contact us formula.
Unfortunately never get a response.
My someone knows more about the active of bimmerlabs.

Would be very nice if you could answer here.
Thanks a lot

To be honest you might have better tuners over in DE, however I know Active Autowerks in the US have a fantastic, tested, and reliable tune for N52 series engines that people seem to enjoy. You have a 330i with the 3-stage intake manifold so you should benefit a significant amount from that, plus bolt-ons.

Does TUV restrict tunes as well, or only physical parts?

Because OP has a 330 with 3 stage, the stock ECU already takes advantage of the 3IM, meaning the net gains of a tune will be lower than someone with a 328 (who does the 3IM swap).

Without other mods (headers, MILVs, etc), I'd expect the tune alone to net 10-15hp. But it does help with power delivery across the power band, and improves throttle/shifting in AT cars also.
