Tunes/trans

[mac]

I currently have an Evo with canned tunes and run on #2. In Oct I ordered an 87 Performance tune which I am waiting for. With all of the various questions and concerns noted in the different forums I gotta say I beginning to worry abut programmers. so I will ask, my truck is an 07 S/C FX2 4.6 with 3.73 2 wheel drive, daily driver no towing. What problems are related to the above senerio???
