2004 audi s4 real max power ?
As per title, just bought a tidy 2004 s4 saloon which is in need of some love and i am wondering what are the max power gains that can be had from the v8 NA engine ? It's missing a few bits: front centre armrest, had RNS E at some point but has been removed and it looks like it's been mapped at some point- the engine is rather loud with the factory exhaust ! Good thing is a manual and with a few cosmetic tweaks it can be made a looker ! I wasn't in the market for a powerful v8 saloon- an estate would fit my bills a bit better but i will give it a try for a little while ! The engine is healthy and is quite low mileage, will post a few pictures when i get it back home from it's previous owner !
