How does one tell if they are already on the car? Is there a part number? I dont think color is relevant... or is it?

 

JCW injectors are blue and black in color.

Stock injectors are tan and black

 

I found this number and from what I remember is that the injectors on my car are a pale blue... this number is the one from the would be stock injectors Siemens Deka 1521390

 

Now im certain I have the JCW injectors... i wonder if the did a tune on the car as well? can they just be put on the car without a tune?

 

The stock ECU/Tune will adapt to the 380's with no problem. The only way to tell for sure if your car had been tuned or not is for one of the tuners (Jan, Mike, Way....) to somehow get a download of the maps in the ECU. (Don't go to a dealer!)

 

bump...is there a way to download the ECU map?

 

With a remote tune tool....
but even then only a pro will have the software to unencrypt it to look at it...
