Default Converting a 98 tune into a 99

My 98 computer in my mustang died on me so I re-wired the car to a 99.
unfortunately I am not able to get the tune to work and was wondering if anyone has experience converting the 98 tune to 99?
Here is my original 98 tune. The stock tuner that came on the 99 computer and my try at converting it. The car will run a couple second really rough and then die. I believe I have VATS and column lock off already.

The tune is on NA 408 with a th-400 behind it, running a 99 Corvette wiring harness.
