So I'm a recent convert from the e46 M3 world, mainly because the XF sounds AWESOME and it's German powered! Oh yea, these things are a blast to drive.

Anyway, on the N/A car I will need more power.

My modlist:
Magnaflow exhaust (delete rear cats)
Needswings dual CAI
Benz V8 TB 74mm

Now, to round this out I believe a tune is needed... Is there one I can manipulate from my laptop, or how does it work? Is there a concensus on which one is the best for a NA car with the above mods?

Thanks in advance!
