1971 Scamp performance

Do you suspect any issues with the MSD? I ask because I just replaced an ignition module in my 86 Mustang GT the car was somewhat of a dog off the line before and now its like it woken itself up. Ford TFI though when they go bad it sets the computer into a default timing mode, and I suspect that was the case . But your timing off the line and through the advance curve is what I am getting at. I would see if the MSD unit is set up correctly or if there is adjustments etc.
