Default ECU/software flash - newb here

So school me. Leased 2013 A4 - 2.0T w/ 8speed auto tranny. Putting the tranny in S mode with the stability control Off/Sport mode already transforms the vehicle. Looking to do an upgrade for performance but also to help MPG. My highway mpg in 8th gear I am very satisfied w/. But to sell the idea to my GF, savings in gas or increased MPG would make it a possibility. I don't want to go anything exchaust related. I posted a thread about an intake for a little extra performance and MPG, but the more I read, the more I see that the right software flash really does wonders for these 2.0T's performance wise. I hear it's like a whole different vehicle. Two main issues is.... does it help gas mileage? And is it detectable when going in for a service? Car is leased for 42 months so I guess I would have to reflash the stock ecm before turning it in, or maybe not even have to bother...? School a newb :P

Ecu tune will be detected by the dealer. No way around it. IMO I wouldn't, unless you were planning on purchasing the vehicle after the lease.

yeah tunes can't be hidden (ignore claims of of "stock mode" by tuners). They will be able to detect it when you get the vehicle serviced.

i haven't noticed a significant difference in the amount i spend for gas after getting a chip even though the mpg is supposed to be better. so don't buy it for that reason. its a performance upgrade, thats the reason to buy it.

p.s. i dont think you can modify a leased car, unless of course you are trying to do mods secretly. if so, good luck.
