Wondering if someone using SGII can post their EBP readings. Trying to troubleshoot, MPGS seem to have gone down as well as boost.

KOEO 14.7
LI 17
HI 20

While going up a hill I got boost to 26.6 and EBP was at 50

 

Ok with the catalytic converter and muffler off, the numbers changed a little.

KOEO 14.7
LI 16.4
HI 18

Wonder if the cat and muffler are too restrictive.

Anyone have a comparison?

 

Just make shure the numbers are taken exactly like this
Truck in PARK OR NEUTRAL all times during test
ECT at 190* or close to And EOT at 185* or higher
-------------------------------------------------------------------
KOEO=Key On Engine Off =record value
Low Idel (truck idel on its own)=record value
High Idel (2500RPM)=record value
Values below are given in this order^^^Left to right



IDK how you came up with your numbers but if you did it like mentioned above the YES EBP was to High

EBP to high could be from a Bad sensor or Plugged exhaust

Start by checking all Pressure sensors against one another at KOEO they need to be same at KOEO

so at KOEO check BARO,MAP,EBP need to be same PSI at this point


I am leaning towards a Plugged exhaust since the numbers did get better when you unhooked the Exhaust

 

Koeo sensors are the same

Cleaning ebp tube and will repost

 

Numbers earlier were with temps greater than 190* with truck in park in my driveway (except the one with boost). MAP, BMP, EBP all within .4 psi at KOEO.

After posting the set of numbers without the cat and muffler, I tested again and got readings that were very similar to numbers WITH the cat and muffler. This made me realize the sensor and tube were dirty and must be giving erratic readings. Before, my thought process was that if the EBP tube and sensor were dirty the pressure readings would be lower not higher. That is why I took off the exhaust system to rule out a restriction in the cat and muffler. Plus I hadn't cleaned the EBP before, so it was easier for me to start with the other part first.

Reattached muffler and catalytic converter and cleaned EBP sensor and tube. After cleaning, I turned the truck on to hopefully blow any remaining crap out before putting the sensor back in. After cleaning:

KOEO 14.7
LI 16.8
HI 22

Keep in mind, that is with the cat and muffler back on. If I get time tomorrow, I'll test again with them off just to see.

Took a test drive and let me tell you something: My truck is back! What a difference. I know, it doesn't show from these numbers but there is a huge difference in the way its driving. I first noticed this all after my EGR valve plugged up. Seemed to be lacking power, but I chalked it up to the turbo/pcm relearning the new EGR valve and the system still clearing out all that carbon.
