The speedometer in the Marauder is off. It reads 15% slow. What would cause this? all of the tires are stock sizes, i dont know if the car has gears in it or not, i believe it to have some kind of flash tune based on ths shift firmness. I would think the speedo on this car is run off the ABS sensors, not the OSS gear.
Any thoughts on why it would be off?
