Hmm...I've made posts in the past about this, but it's been a while since I looked at Syracuse, so I'm not 100% clear. They're extremely similar, so you're not exactly missing out on a TON by using Syracuse rather than Tulane.
Okay, first things off the top of my head. In Tulane's playbook, they have a Wildcat like Syracuse. Tulane's book has all of the Syracuse plays plus one more, where the player who takes the snap hands the ball of to the guy in motion...who then turns around and throws it to the player who took the snap as a screen pass. I think it's called a QB screen or something.
Both books have 2 Strong I, 1 Weak I, but Tulane has four I-Forms to Syracuse's 3. One of Tulane's I-Form is Y-Trips, which is an excellent running formation once you use the proper formation subs. I use it as my goalline formation.
Additionally, Tulane's play book has the nice Pro-Split formation (QB under center, HB behind LT, FB behind RT, TE, and WR to either side). It sort of combines the best of Ace & I-Form, in my opinion, and is a great formation for getting the ball to an athletic FB in space.
