I called carbahn and spoke to there tuner and he confirmed that xhp tune is not supported with there tune
I think because they provide factory warranty option to purchase with tune so that's why they don't want people to push there cars to full limit and cause issue with engine and transmission.
Now I'm completely confused 😕 to decide if i should go with carbahn or not.

That's exactly what happened to me. I'm torn between RK, ECC, and Carbahn. There's a recent dyno posted in the g30 5 series forum, a m550 posting like 608whp with Carbahn. Only an intake an midpipe, so that's actually really good numbers.

However, the tq per gear can be controlled in the xhp app. If I do Carbahn, I'll just set first to stock (750), and each gear 10% higher until like 1075. The tq levels will be likely higher than advertised then. I just can't help but think Carbahn's tune is just a rebranded ots tune, simply with some higher boost.

ECC seems good- really high numbers though which is scary.

Ya carbahn told me the same thing but they just need the tq levels back to oem which is 750 per gear. That can be set in the custom settings in xhp app- really easy to do.

I shipped my DME's to dme tuning coz there software supports xhp without any changes

Ya probably the way to go. Are there any customer dynos available? I hear a fair amount of people that go there but have not seen the n63 customer dyno or draggy.

DME's just got shipped today to Finland from DME tuning. I can’t wait to get them back unlocked and tuned 😆

Your M50i is going to be sick when you get running with a full ECM tune. Guessing around 700HP from what I've seen the 5 and 8 series guys getting from the N63.
Look forward to hearing a full report.

Tuner claims 720hp in stage 2 but with the amazing CA gas I'll be happy to get 690 🤣

You spoke directly with the tuner at DME? Their stage 2 says 700bhp but there's no dynos anywhere to support their advertising. They also said they accommodate xhp stage 3?

postbox1918 wrote

Yeah i spoke to him directly Dme tuning NJ not the one in texas and he told me that his tune supports xhp stage 3. I mentioned you earlier that he tuned 2 M5 competition for my brother so thats why u went with that company. I read it somewhere that if you have bm3 or mhd license then euro performance center also provide service to get the ecu unlock through femto and then you can tune at home with bm3 or mhd

When is the big day?

Lol I'm waiting for an update from Dme tuning . My car DME's were shipped with bunch of other DME's to femto on last Friday .
Next is to sell my 21" OEM wheels and upgrade to OEM 22"s.

I'm basically waiting to see how this turns out. I'm really torn between the 3 tunes: rk, dme, ecc so if yours hits in that 720bhp range, I'll do dme.

The full flash tunes are all going to be close. Driveability and a linear power delivery are what you should really use as a deciding factor for choice rather than a peak HP # which can be artfully manipulated by a savy operator.
