When I start the car it surges up to 2500 for a brief period then idles down; im still learning MS but I'm cautious to changing too many things until I absolutely know the program completely....how can I stop it from going up that high upon startup?

check out the cranking duty % it will move from this value to the idle value over a period of seconds [stock tune usually uses 9s]
