I have a 2009 cobalt 2.2 lap that I supercharged. used all of the stock cobalt ss parts(pulley, injectors). Right now im having an issue just converting my current tune to match injector data from a 05 cobalt ss/sc stock tune. Anyone have any insight on scaling the injectors? I have changed my axis to psi instead of kpa but cant edit the values and the lowest value on my tune is higher than the highest value on the ss sc stock tune. Any help or advice is appreciated!!
