SIEMAN DEKA 107961 60# EV1 INJECTORS 99-04 FORD F150 SVT LIGHTNING 02-03 HARLEY DAVIDSON SUPERCHARGED

Adding an aftermarket Supercharger/Turbocharger may max out your current injectors. The fuel injector flow must be matched to the airflow requirements of the engine over the entire rpm operating range. The injectors must be able to supply a large amount of fuel at wide-open throttle to prevent high rpm lean out, and transitional amounts to cover all of the operating conditions in between. Supercharged engines in particular place even more rigorous demands on an injector range because of their increased airflow capability.
