Is anyone working on piggyback tunes for the 550i N63 engine?
I currently own a 335i and I'm thinking about my next vehicle. I have a 528i loaner at the moment - and I'm really liking it. And it's a 2009 - not even the new model. I'm interested in either the 535i or 550i - and wonder which will be better to modify.. I'm sure there's more going on for the N55 right now - but what might things look like for the N63 in the not too distant future? I'm sure somebody must be working on something...
Any thoughts?
