U7193 04 Sierra 5.3L tranny settings help

Just had a new tranny dropped in my truck and its a Jasper so i can't do the usual vette, billet, and shift kit that i love! What can i do with the shifts to make them firmer and faster?

you can add some line pressure to the tunes for firmer shifts, but there is no reason you cant add a servo, etc.

Thanks
