Are you asking about the B7 or B8 model years?

Sorry for the typo, I just noticed that my title said '08 but the message said '09... It is a B7 '08 that we are talking about.
Cheers!

It sounds like JHM is a little more hardcore, and I like that... But I wouldnt be willing to void my CPO warranty for any mod. Once thats expired then I'd go that route. So until then I'm stuck, as APR doesn't have the programming/calibration in place for the Simos 6. Why did Audi switch from Bosch in the first place?

dunno. it's not Audi's fault, it's APR being lazy on a tough to mod platform. They use Siemens ECU units on all the new cars I belive. They just changed suppliers. (Simos=Siemens)

anyway, just be happy that you won't waste your money!

best tune for a B6/7 S4? DOWNPIPES

Bare minimum, gut your precats for a solid torque/hp gain. You'll gain more than any off the shelf tune. Or go with 2.5" downpipes. Based on your warranty concerns I reckon you won't be a fan of the 2.5" idea, so gut the precats on your stock downpipes and you'll be happy.

then get a 2.5" catback with X-pipe.

THEN get JHM's tune, which needs upgraded exhaust in the first place.
