328is tune recommendations

I am looking for an advice on tuning options. Here is where I am now:
- 328is, 1999, last month of production (a BC car, no rust)
- manual
- S52 cams installed
- M3 exhaust installed
- Fan deleted
- M50 intake installed
- Stock M3 injectors
- Stock MAF
- Stock intake (No cold intake yet)

Tune options I have found:
- Shark Injector for M52 engines with S52 cams, M50 intake, M3 exhaust
- Stage 3 option, $349
- AA tune. I cannot find much info, their website seems to be down but forums tend to recommend AA over SI
- Kassel performance DME (
- not much info available online

And than there is a local (Ottawa) tuner,, recommended by Shawn Bernier (Metric Homes).

Any suggestions welcome.

If you have a local tuner, I suggest looking into his options. Usually the logistics of getting it done is much easier and worth the time/cost savings.

Additionally I suggest looking into:
They are well known on R3vlimited and the m5x swap guys as making good power with those motors N/A & FI.

I ran an AA tune with that set up and it worked well, S52 ECU had the same peak hp but the curve was slightly worse. You could reach out to Epic Motorsports as I'm sure they have something that would work for you and I've heard their customer service is pretty good.
