EBP seems high

**Fantom** · #1 (**permalink**) 01-27-2013, 10:04 AM

Not sure if it's normal or not, but at idle and 0 boost, EBP is showing 2 psi. Cruising at 50 mph or so, boost is showing 3-4 psi and EBP is 15-16 psi. Does this seem high or is it normal? If it is high, what does a high EBP reading mean?

I am reading this from my insight CS

EBP must always be higher than boost to promote positive EGR flow, otherwise boost will flow into the exhaust and cause all kinds of strange sounds.

Gotcha, the 15psi at only 3 psi of boost had me concerned a bit.

Sent from my phone that somebody didn't help me get.

Your EBP is reasonable, but it depends on what tune you may be running, engine load and the subsequent vane position.
