new and interested in the S-5.

OK guys I am in the military and working TDY in Germany until Jun. This is my retirement present, some guys get guns, watches, plaques. I get 8 months TDY in germnay!
 
I have been swapping out rental cars once a month since Sep. I had an Audi A-4 that handled the best of the lot so far. The Ford Mondeo is actually holding its own but I don't see the US having a car like the Mondeo any time soon.
 
So now I am in the market for an S-5. The question I have is when I have it delivered to the States in Jun what tuning options are available? The reason i ask is the S-5 has 350ish whp from what i can tell. The RS-4 has the same 4.2L motor from all indications. Is it just a matter of reflashing the ECU or plugging a piggy-back device to extract the additional power? Any help will be appreciated.

Thanks for serving our country, welcome to AF.
 
Good choice, you deserve it!
 
There's lots of mod options, check out the S Model Section, and some of the others under Audi Reviews.

that car is bad ass, i got to drive it on the track for 2 laps at the audi driving experience at infineon race way, awesome ride feels prefect!.  i want one, bad!

I'd love to test drive one. They are selling fast here. The military sales program starts reselling in April. I did make a trip down to Saarbrucken and they have a white R8 on the showroom floor!
