Burger - BMS Stage 1 - Good or Average?

[ckroeger]

Hi Everyone,
I'm interested in opinions from people who have experience with the BMS Stage 1
Tune. I have a stock 2105 M5 CP.
For the people who have experience, does the car run smooth, shift well (DCT), is it worth the HP Gain?
Any comments would be welcome.

I wouldn't ever use another piggy back after my experience with Dinan; OBD port tune will be better.

It's a nice inexpensive option that adds 40-50hp. It won't match up with a JB4 or full ECU tune but the install time is really quick and it's easy to remove also. It runs as smooth as factory.

I have bm3 stage 1 tune with grill intakes.

HUGE difference than factory, less turbo lag, better throttle response.

can't tell how much more power it is but I assume with the intakes could be close to 100hp at the crank
