I'm currently chipped with stock, 91 and 100 octane programs on my b5 (ecu 557p or the nonDBW). I'm planning on installing a K04 upgrade and realize i would need to change my programming.

Wondering if APR offers K04 programming for my model, and if they do, has anyone had good experiences with it?

no they do not. they only have k04 for transverse engines for vw. audi is diff story.

you might have to switch to giac or upsolute. how was your apr installed? flash or socketed?

let me know how this works out. i also had my chip socketed and might be doing the same as well (switching software after i get a k04)... but i'm just a bit worried that once they resolder a new chip, it might cause damage on the board.
