i have a 2001 a4 quattro with the trip and 1.8t. i want to upgrade the ecu and eventually the turbo and all that. Any recommendations of where to start? i dont know a whole lot about audi's and this is my first "mod project." im looking at RICA from eurosport tunning or APR for for an ecu upgrade. Any thoughts? thanx!!

 

Go to the B5 A4 subforum and read the FAQ, as well as the turbo guide by CincyTT in the TT section. They'll walk you through all of it.
