chevrolet performance ecm vs acdelco ecm?? need help asap

I need a new computer for my 89 bird with a Fully built up 350TPI with a custom chip. Does anyone know the difference between chevrolet performance 88999194 and the acdelco 88999194? Except the price. Thanks

No difference in the actual ECM. Maybe the Chevrolet performance ECM includes a MEMCAL?
