Some ECU allow a second boost sensor upstream of the throttle body (Bosch Motorsport, MoTeC M1 etc.) . Many OEM's use a boost sensor upstream for boost control.

What are the benefits?

Excellent question, I am very interested as well. I have done a little research on the subject but didn’t come up with much.

Anyone have feedback on this?
