So I finally pulled an A9L out of an 89 LX today. Attached to it is a Hypertech Power Module. There is a sticker with a part number on it is 689021. I don't know anything about these sort of things. Can anyone tell me anything about it? Is it good?

Part number says Hypertech power module for 1989 Mustang 5.0L M/T except CA emissions
