Somebody check my pulse. Is this true? You can upgrade a 1.8T up to 268hp and not void your new car warranty? Please elaborate on this one. Does the dealer have to perform the upgrade? Do upgrade packages have to be approved by Audi? This just sounds too good to be true. 'Confused' -Robert 96 Jetta GLX 86 Jetta GLI (quattro-less for now)
