[335iPSI]

I really hope we are able to use any of the latest tunes here in the US for the X1. My big hope would be that they do bring the X1 M35i over --- and with the N54 like in the 335is. That way, there's a good chance that my current Procede V5 and meth would slap right in! What a great all-around vehicle that would be. A nice 400+whp --- I can dream.

The other option would potentially be the Stage 1 N55 tune that BMS offers on their JB product.
