Is APR Stage 2 The Last Stop?

[on3eighteen]

Now that I have the APR Stage 2 w/ pulley on my 2012 A6, I'm trying to figure out if there's anything else I could do to squeeze out more power. 2 things that come to mind are exhaust & a cold air intake. I'm curious if you guys think there's a significant increase in power w/ either of those 2. Honestly, I am having a hard time finding a cold air intake package. I've seen many replacements for the air filter but from what I've read that's mostly for cosmetic & audible super-charger whine vs. raw performance.

Take a look over at the B8 S4 section. Seems like the next step eventually will be a dual pulley setup once the tuners make tunes for it. Most of the guys over there that are running dual pulleys are using e85 atm, so not sure if there's much to be gained on regular pump gas. I stopped following it very closely once i sold my S4.

I have an a6 as well but no tune yet, if I decide to keep the car I will go stage 2, dual pulley and meth injection. lots of good info on the S4 forum.

If you want more than straight stg2, then yes, dual pulley with an e85 tune and/or meth injection. Outside of that, you could upgrade the blower to a TVS1740 or something but not many have wanted to spend that coin for not huge advances in power.

There are people using dual pulley and running a ecu tune + piggy back at the same time.

We have dual pulley tunes and dual pulley with E85 as well.
