The car runs in closed loop while at idle, cruise and light throttle applications so in theory everything should be the same. I'm not going to get into a discussion about different brands of products being better than others as opinions are like a##holes, everyone has one. I have fitted or tuned lots of turbos using a common type of injector and different cars appear to have different idle qualities no matter what is altered in the tune, I'm not against using this common type injector as they are good value for money, in fact my wifes car runs the common injector. I'm glad worn is now even happier with his car, but the aim of replacing the injector was purely for the liquid gas compatability, nothing to do with how the car ran or performed
