The way to go is to first connect your nistune data cable. Pull the maps off of your ROM tune and then put the rom tune data into your Nistune board. Then fine tune from there. It eliminates the need to mess with your timing maps, for now. If your messing with timing you really need to be on a dyno. In addition, it eliminates the need to do anything really because your rom tune --> to nistune is the same as your rom tune was to begin with. It gives your tuner a good base map to work with, and allows you to drive your car before you get it tuned.
