All the items are in great shape. I only used the NProbe two times. It is a great tool for diagnostics and datalogging. The Mass Airflow has 160K on it. I have never had any problems out of it. The HKS S-AFR has been in the car for about eight thousand miles and has worked great. The ECU is programmed for a 91 5-Speed with 720cc injectors and a dual-pop. If you have any questions or are interested in the items email me at sleekz@aol.com
