Jeep Strokers

So I have an interesting issue, reading the fuel sync with a MT2500 (had to tell it the jeep was a 5.2L to get it to show up) I am getting 15 degrees instead of 0 with the distributor in the stock location? Any thoughts on why this would be?
I have always thought my jeep was not putting out the power it should be, could this be the cause?

Cheers

Since you have the mt2500 I would play with the sync and see what happens.
