BMS vs AA

forever_speed · 03-21-2012, 08:48 PM

I'm looking to upgrade my 06 325i ECU mostly for throttle response and a little more kick. I'm going to be running stock exhaust and air scoops....eventually will be upgrading exhaust. What are your experiences with these? What is the gas mileage average with the tune? I will most likely run the race map at all times.

Thanks guys!

TONS of these threads already in the NA section,

AA - True tune
BMS - Piggyback tune

AA tune has always been, and always will be the better of the two.

Yes,I apologize new to e90post. Whats the process of getting the AA tune? you have to ship your ecu to them?

The AA tune is an actual ECU flash, the BMS is an overpriced throttle relay enhancer.
