if I still dont feel anything, do I have to renstall the stock file 1st then install the tune...or can I just install the tune file again?
I think AA can probably answer your question in more detail, but you car will need to adapt to the tune over time. 50 miles might not be enough for the car to adapt to the new software. I think my 325xi had a notable increase in power with the euro box, intake manifold, AA tune, and PE.
