Hey guys I have been looking around to do some upgrades to my RS5 but I'm not interested in changing my exhaust or headers.
I want to keep the car as stock as possible and the only two things I want to do is an ECU upgrade and possibly change air intakes and filters.

Although I have been searching everywhere it seems that there is nothing for an RS5 besides a full exhaust kit or some pretty fancy (and expensive) air intake systems. I haven't find absolutely nothing in regards ECU.

Anyone has an idea where to look?

Thanks!

Where did you look? APR is currently the only one. This is a naturally aspirated engine, so an ECU upgrade isn't gonna get you much. Not worth getting flagged TD1 for a little bit of gain.

My thought behind it is the fact that you can get better gas mileage on the highway since I'm driving daily around 60 miles.

Well, again, the possible slightly better gas mileage is not worth gaming your warranty. APR doesn't even make any claims about better gas mileage, other than they paid attention to it and depending on driving style and fuel quality, better miles per gallon may be achieved. Keyword being "may". This is not a 30+ mpg highway cruiser and never will be. If gas mileage is a concern, you frankly bought the wrong car.

I know it is not a 30+mpg but at the same time I'm not driving my car all day on the redline, so for those hours that I'm commuting I would like to push my mileage as much as I can. This is my daily commute as well as my fun car.
I will not do anything to it until the warranty is done.

I think you'll make more of a difference by adjusting your driving style. On road trips for example I use adaptive cruise control and comfort mode, which pretty much achieves close to the stated highway mpg. I don't commute, but this is my DD. With a long commute like yours I think the S5 would have fit the bill better. Still a fun car, but if you drive it conservatively by keeping it out of boost it will deliver significantly better mileage.

It's a huge addiction the RS5! I had the opportunity to get the S5 but I drove it and it just wasn't enough I guess. No worries, at the end I'm not going to do anything until the warranty runs out, just exploring early on the different options. Who knows, maybe I will go all mad and do a full tune on it.

That it is. The S5 didn't do it for me, either. I was reminded just how much different the RS5 is the other day when I had an S4 loaner for the day.
