Where are all the modded C5 RS6 at? 500awhp to 800awhp+?

[RS6Goals]

Your efforts would be better directed towards a C7 S6 or better yet an RS7 if you're into the sportback look. What you will spend in time/R&D/buckets of cash chasing this rabbit is readily available for that platform.

If you stick with the C5, tune it to a proven 525-ish hp, keep up on maintenance and enjoy it.

Im not following this logic. Unless im missing something isnt the c7 s6 only rated at 420hp? so even after a chipped RS6, s6 is more money for slower?

and not to be an @$$ but did you really just bring up a RS7 into this, I mean the price difference alone...I don't know about your financial situation but I certainly cannot afford a 100k car
