If you create a script from comparing a stock tune to another tune, then run it on a DSP5 tune it will change the base tune only. To initially make a DSP5 tune you will have to copy and paste the tables from each tune you want into that DSP folder. Once you have made one you can create a script comparing a stock tune with DSP5 upgrade to the completed DSP5 tune - then to do the same tune for another truck you would upgrade their stock tune to DSP5 then run the script.
