We have an old Cadillac like 91 and we put a bottle of alcohol in the gas tank when we need to get the emissions tested

Odd you can't pass emmisions, engine hot enough ?, Cats are bad ?

have you tried it with the stock maf back on there? My guess would be your tune is a little off.

You have the OBD2 plug test? I pass emmisions in TX with long tubes and a ORY since my rear o2's are deleted.
I have the Granatelli MAF, so I can't see that causing it. You have long tubes and a tune, so your rear o2's should be deleted if not have the tuner you went to delete them so they no longer read when the plug the OBD 2 in. I had mine deleted since I have no cats.
Only thing I can think as your tune is set too rich(have to go get the tune redone).
