Nissan Pathfinder Performance Programmer (WD21) 1985 - 1995

Tuning your Nissan Pathfinder for maximum performance with one of these performance tuners is a great way to increase horsepower and gas mileage. Nissan Pathfinders use a simple plug and play performance tuner. Most later model Nissan Pathfinders use a plug and play re-programmer while older Nissan Pathfinder ECUs require for a replacement chip and custom programming.
