[BR3W CITY]

Starting at $650ish, you really want pro so it can have external Wideband interfaces directly into the box. Makes logging easier, and pro can log without the laptop attached for street tuning.

Credits are depending on the vehicle. Late model Fords for example cost more credits than some others because they use a predicted virtual VE system. Diesels also cost more. Most GM vehicles are 2 credits, Fords are 3. If you want a custom-os for doing 2 or 3 bar, or SD, then its 3 credits.
