Hello, I shark injected my car a few weeks ago, and i was thinking of picking up a 3.46 differential for my 330ci. I was wondering if i can install the differential without the software being affected? Thanks.
There isn't much horsepower and torque gain, but it is definitely noticeable. I got it mostly for the better throttle response and the 7000 rpm redline, and it makes a huge difference there. Overall i'm pretty happy with it.
You will not have any issues with doing that, actually it'll be a great match to the diff taking the revs higher.
