Getting ECU upgraded, what should be double checked?
I have a 2001 1.8T Auto with 30,000 miles I am going to be getting APR software installed on. Given it's age I'm not sure what hoses and such I should double check to make sure they are in good shape, considering the extra boost pressure involved. Everything I can see look and feel okay to me, though I am inexperienced. The car has been garaged and is in pretty good shape in general, though the mass airflow sensor, and an engine coolant temperature sensor has had to be replaced.
Any tips?
