Anyone here with ACM burble flash tune?

Looking to get myself ACM burble flash tune possibly with or without DP.
I'd like to know if anyone can chip in their review of ACM tune.

ACM has been producing amazing tunes and power. +1 for ACM.

My only concern with the burble is whether it has any adverse affects on the waste gate. Premature wear or anything like that. Definitely worth asking.

Great choice for a tuner

I do see ACM branched out to the west.

And concern over the wastegates among other things would be justified. There's a reason the S63tu doesn't have over-run pop most of the time and it's hard to conceive a way, even in theory, to program it in safely without the same significant hardware modifications the S63TU2 incorporates to allow some character to come out the ass.

ACM west uses Gintani's shop/dyno resources. No affiliation past that. ACM tuning is from us here on the East coast

Convenient.

Now, how detrimental is this since:

- Overrun pop requires combustion of unburnt fuel downsteam of the cylinders

- The wastegates cannot open fully on pre 7/14 builds (no full electric wastegates were ever added to the S63TU but the exhaust manifold was modified to accommodate the updated electro-pneumatic wastegates with revised spring rate and longer actuator arm range)

- There are two different versions of the DME's and aren't interchange (MEV17.2.8 and MEV17.2.H)

- Valvetronic keeps positive pressure during off throttle cylinder de-activation and eliminates the need for a Diverter of Blow Off Valves, the compressor stays partially spooled, and scavenging is maintained without the need for a fuel rich ALS (unique to the S63TU in Fxx M5/M6) which is why it's the only BMW engine that doesn't have overrun maps with popping.

There is definitely an influence in this vid. Whether it's a surge in the turbo manifold or a stall from pressure coming backwards out of the DP's...no clue. Doesn't sound healthy though.
