I have an extra set of injectors in the garage in a ziplock bag, they are 009s. My car has 3” dp hooker exhaust and a cam. Do you guys think that the 36lb ers in the car already are enough or should I install the 42lb ers. If I should install bigger injectors, since they have ben sitting for about 5 years should I get them checked out or tested? Who can do that type of work? Ive heard of injectors getting flow tested or matched. Does that sound right?
