A4 1.8T (B5 or B6) tuning questions
i'm seriously considering purchasing a GIAC chip from AWE Tuning, because the hp and tq gains are awesome. I'd like to talk to someone who has moderately tuned their A4 with a GIAC chip.
also, what other mods other than exhaust and intake should i do if i want to get the most out of the stock turbo? is a diverter valve a good investment? what about new intercooler piping?
