You can get adapters to make the box fit, but the MAP sensor voltages will be different so the boost values would be off. I don't know how much of a difference this would make, but the 98-00 trucks have different MAP sensor voltage readings than the 01-02 trucks. I'm no expert, but I know they are different. Maybe call TST or Edge to get the specific details. Maybe this is something that can be reprogrammed fairly easily?
