depends on what you use. instead of using just injector cleaner go with some seafoam. it cleans out all the carbon. and another good name is lucas, stp.
or if you are going with a octane booster go with some, NOS, stp 101, but be careful some of the labels will say 30% on them..for gas mileage. stick with brand names
