I always thought they were red/brown looking.

Just asking cus some guy I'm helping tune has some "dsm 390's", but they're gray/silver.

He say's that he's ran them without a problem before on his old setup.


Also, should I just leave the stock injectors selected under the battery offset?

the set up is a stock b18b with a hefty turbo

 

There grey
b390L is the code on one of the sides.

 

Yep those are it right there. I've got a set myself.
