Hi all, I am the proud owner of a new to me 2015 S3. I am planning on tuning the engine and transmission so that i can have a bit more power and responsiveness. Is there any other mods that you would recommend? Other things that i had on my mind were downpipes, sway bar, and maybe exhaust someday (it already sounds nice and throaty IMO) I just wondered if there is any mod that is not on my radar and i should consider. Also, the 4 cylinder engine seems to hold up well for the long haul ( i actually want to keep this car for a while that is how much i like it). Thanks all!

 

Update, I am going to do ECU, TCU, downpipe, and intake. Very excited. Will report back since there were so many responses. Seems like an active forum!

 

Mods done. Wow is all i can say. I liked the car prior to the mods and i love the car now! Do i see an APR stage III in my future or do i save the money and put it into the RS3? First world problems for sure.
