My 2000 Audi A4 1.8T has an Evolution Motorsport intake, Neuspeed exhaust, and sway bars. I have 18" wheels also but that is of no importance to me as of the moment. I would like to upgrade the turbo, get an intercooler, chip, diverter valve, boost controller, etc. I obviously want to make it really fast. I just do not know where to find the least expensive/high quality stuff, what brands to use, or what other mods will help increase my performance. Can anyone help lead me in the right direction/s??? The help would be greatly appreciated. Oh, one more thing, my brother says that besidesw chipping your ECU, you can actually send it in to have it programmed. Is that true?
