On the other hand (and a big part of the reason I personally dont see a need for one), are your own posts that impressed me -- as you stated "my F10 M5 is the fastest non-tuned car I have ever owned," and your 1/4 times with a bone stock M5 are amazing!
If I ever considered a tune, I would really want a lot more certainty that it wouldnt create a warranty issue...
If I didn't have that worry, I would go with the swtizer piggyback tune... why? Because he and Dave posted up real videos that show real performance increase on the road, not just a Dyno change. http://f10.m5post.com/forums/showthread.php?t=854869
, but as Niko stated -- its not for the faint of heart.
Now if you drop a tune in on yours and break into the 10's on the strip that would be interesting too.
I thought about tuning mine but there really isn't a tune out there right now that I trust...and I don't want to be some tuner's guinea pig. But if a reputable tuner puts something out there that is reliable and can quantify the gains...and will provide some sort of warranty...then I would probably pull the trigger. Until then, I will try to see what it can do without a tune at the track.
