It's how I hear people describe their Audis.

 

Oh man.......well you will get a lot of opinions on this.but it varies

Stage one is Chipping,

Stage two is with chiping and some supporting mods,

Stage three is all of the above with intercooler, exhaust fully outdone and rebuilt engine and a BT kit


these stages vary from user to user but the above is pretty much a guideline

 

Kind of like first base, second base and third base?

 

Pretty much, but depending how far along you are on those then there is Stage 1+, 2+, 2++ and etc....
