1988 WSP SSP with mass air

[a50ina50]

My 1988 Washington State Patrol SSP has a mass air meter. My understanding is that all 87&88 Mustangs had speed density. Unless is was one that was sold in California. Then it had mass air. Then in 1989 all Mustangs had mass air. I guess my question is does anyone have a 1988 SSP, non California, that is mass air? Mine runs fine. I've had my 1987 Notch for 10 years. It has speed density. I've never had any issues with it.
