DBW at this day in age is reliable for the most part (Aside from boosted Dodges) Subarus have had it for a while and I don't have a problem with it. Typically manufactors do goofy shit with the dbw tables to make the cars feel diffrent.
Subarus dbw map for example looks about like a supra dyno. LAZY LAZY LAZY ZOMG OPEN THE PLATE!!!!.
