we made my car map on the road. Get a long cable and get the controller and the laptop connected (laptop inside the car).
then it is a game of trials.
Start with boost on minimum, and start with a rich map, then watch your afr...start modifying your map until you reach the best afr (11-13) all the time.
Note that you have to push the car pretty much to the max (full throttle) to cover the whole rpm range.
you cant just take a map from someone, every car would have its own since the kit you are using is custom made
