ive asked this before and after having 2 cosworth ones and 2 ERST ones i think they are different.
The cosworth ones are black and the ERST ones are brown and when i put a cosworth 1 on my ERST i can controll my boost but when i put a ERST one on i cant controll it.
Dont know if that helps just what i have experienced.
