IIRC Johnson modifies smaller injectors by drilling out the tips, if done carefully the results are somewhat predictable as far as flow volume but the spray pattern, well lets just say it is similar to removing the spray nozzle from your garden hose and letting the water free flow. Some guys have great luck with them, a few have not been able to tune them all that well, I have a feeling alot has to do with cam timing and how much exhaust reverts back into the intakes to help evaporate the fuel puddles. ;)Originally Posted by MikeyMustang
