Hello all!! Just sold my highly built BMW545i and got myself into a 2013 S4 Prestige, 19" wheels, MMI, B&O, nav, etc. Basically all options available including sport diff.

Now on to the questions, warranty is not a concern for me.

I have ordered the AWE Touring exhaust system with resonated down pipe (as I have an auto) as well as a roc-euro intake.

(those decisions were based on trolling these forums, and thank you all so much for the plethora of technical information here!!)

I am now looking at acquiring the APR Stage 2 ECU with new supercharger pulley and belt.

Is that the recommended tune for the 2013 S4?

Thanks for having me!!!

Not an expert on Tunes. But lately APR is not getting a lot of love.

I recently had the Revo Techik Stage 1 uploaded, the shop I went to wasn't impressed with APR products.

How would you describe the results?

Found a shop about 30 minutes away that works directly with Revo. Can get the Technik Stage 1+, new supercharger pulley and belt, all installed as well as installing the Roc-Euro intake and AWE Exhaust for $2450 labor included. Doesn't seem bad at all!

This is the first time I've done an upgrade with software, have always done it the old fashioned way (cams, manifold, headers, etc.), I am really surprised at the results. The increase in torque is throughout the rev band, passing is effortless, where I used to downshift I no longer have to and the mpg has actually gone up by 1.5 miles (hand calculated).

I am just shocked at the amount of claimed hp/torque increase by a simple software upgrade. I have not dyno'ed my car neither before nor after but my "butt-ometer" does feel a difference.

Good luck, let us know which route you went and write us a review.....

Good question. Let us know what you decided on and update with results. I'm interested in APR Stage 2 + APR exhaust system down the road as well.
