Am I just better off keeping the BMS PBX or is the tune that much better then the PBX. I've heard rave reviews about the AA Tune but most people have the 3 stage intake manifold to compliment it and basically completing the 325i to 330i conversion. So Im basically asking, is it worth it or Im just better off saving my money? Thanks!
Just finished reading this before I got here.
Given that it's on an XI-layout, the information should help you out a bit.
I have an authorized shop in the area that can do AA's tune and for the price, it's worth a shot if you really want to push our NA. It all depends on what you want out of your car. Like what you've stated I'll be doing the tune after the 3-stage.
