i`ve got an injector question, are the injectors in the standard ouput motor the same as the high output?
thanks

 

your question is somewhat vague......u dont specify years, but after 03 i believe all are ho's but your 03 has the 8 hole injector used up till 04. 04.5 and up has a 5 hole injector..But for model year 03 so and ho injectors are the same just ecm programing to derate the engine.

 

thank you that also answers the next question i was going to have,
