Hi All,
I recently picked up this new Amplifier from BimmerTech. Though it is a nice upgrade for some and I have heard great reviews I just found that it wasn't for me. It is tuned for my specs as of now but can be very easily updated with the standard f22 tune or you can have someone tune it for you. It has been in the car for around a month and was professionally installed by BimmerTech.
Find more information below.
