I know what you mean about feeling sick about a car constantly breaking, but c’mon. You must have at least 50% more power output than factory right? You put on a bigger turbo, ROLLED YOUR OWN ENGINE MANAGEMENT, AND THEN TOOK IT TO BOCES! Of course your car is clusterfucked now. Maybe if it was a Honda or a Toyota you wouldn’t have some of the problems, but you would still have ongoing problems.
You’ll have to excuse this VW cat for being a bit cynical. I totally sympathize with you, as I know what it’s like to have a fucked car that you just want to run, but the problem isn’t that it’s an Audi.
