I think this is the differance in fuel mpg when people talk about milage. If you keep the second set of injectors closed your mpg go way way up. I wish there was a light that came on the speed-o to tell us when the secondary injectors open. On those long trips between fuel pumps it might be nice to know. I guess its like opening the second part of a four barrell holly carb. fuel milage drops in a big way.
