Are you talking about the injectors that come on the 04/05 models? The Stage 1 for the SRT-4 is just the PCM, nothing else......

the 03 s1 includes new injectors. when the 04's came out one of the marketing hypes for it was that it comes stock with "s1" injectors since they are the same injectors that come with the 03 s1 kit, so people refer to the stock 04/05 injectors as s1 injectors.
no actually it's not stage 1. contrary to what people want to believe, 04/05's DO NOT come with stage one. they only come with larger injectors, which were used in the 03 s1. the ecu's are different.

RE: stage 1 injectors
......and before anybody spends any money on a Stage 1 PCM/ECU, the units are not interchangeable between model years (but you can have them reflashed for a different car in the same model year).
technically that's not entirely true. as long as a 03 can get their hands on a set of stock 04 injectors, the same ecu can be used for 03 and 04. the 05's can even use the same ecu's they will just have a cel on due to the battery temp. a used 03/04 s1 ecu is about $250 and a set of stock injectors about $40, still a lot less than the $500 that mother mopar is charging......
