I have a 97 a4 1.8t quattro with 3"exaust and a vf28 turbo, boost controller etc. i am running 14.5psi at the moment and want to get to around 18-20psi. Can anyone tell me what is the audi capable of?And what do i need to do internally to make it stronger. I am going to be installing a microtech-lt8 computer in the next couple of weeks what will this enable me to run in terms of psi?
Any help or recomendations will be appreciated
