I have a question about chip tuning....Say i went ahead and bought the inmotion chip tuning on Ebay. Do they do a universal mod to the ECU? If i add mods like (Intake, Pulley, etc) will the tunning need to be adjusted? I am actually liking the price of this and may do it soon. I am also going to be adding a needswings intake and probably the ASP pulley at some point, so i want the ECU to be right.
