old dude back in the game … help him

[Oldskooldude]

New here and would like advice on which forum to look into for tuning and upgrading an Audi TT Quattro 03 model I just acquired. It’s been a long time since I did any upgrading to a VW/Audi. Years ago I used Cw vortex but I’m not much of a fan today.
I’m contemplating a big turbo down the road …… point me in the correct direction please
