RE: ecu for a4 1.8t
you dont need anything but some supporting mods would be a good idea.. going to need a different DV, everyone has thier opinion on those but i had the APR chip in my passat and used the 710N from the dealer like $35 good way to save money works just as good as any aftermarket.. i have a evo dv in the a4.. do a cat back as well but you dont really need it.. and if you just want some extra hp with keeping it sounding stock its fine..
