I was going through some old things this weekend and came upon an old PROM. It's for an 87 formula 350. I just can't remember if it's a hypertech or not. IT's been so long since I've seen a stock ecm I can't remember what a stock one vs a hypertech one looks like. It's blue with some brown on the bottom. Anyone know if it's stock or a hypertech? I used to have a hypertech but can't remember if that's it or not. If anyone wants it, let me know. Thanks

 

Sounds stock to me.

Thats the same colors all the stock ones i've ever owned from a maf vehicle are.
