Should I get a 91 tow tune?

It sounds like you have a monochrome Gryphon? (No multi-color analog gauge display?) If that is the case, I'd use the 2004-2008 F-150 Evolution form. The tunes are the same in any case, but with yours you upload them to your unit using Pegasus.

If you bought your Gryphon from PHP, they'll have a record of it too.

Yes i do have the monochrome, i think, it is the gryphon that has the canned evelution tunes. I think i can change the background colors only. Let me know if you still think i should be using the evolution order form- thanks
