I have a 2005 Audi 3.0L Quattro S-Line Trip-Tonic and I'm looking to get some more HP out of it. I haven't been able to find many upgrades for this car... so far i only have an exhaust which definitely gave me a boost because i can feel the car picks up faster and goes much faster. Can you guys recommend some more mods for boosting the HP, i'm hoping to reach 300HP overtime.

 

The 1.8T had more mods, but for the 3.0 if you want something serious, or equivalent to upgrading the turbo on the 1.8t, then get a super charger. that always does the trick =)

 

300 chp is i think impossible without supercharging...
you can do: downpipes, intake (may not gain any hp/tq) and i think thats it.
There is also a chip available, gains of 5hp.

 

PES supercharger...do it and get it over with. And enjoy the whine!

 

PES also does ECU re-programing for an additional 15 ponies i think
