I touched on this in a couple of other threads, but thought I would throw it out here and see if someone can shed a little light on my problem. Looking at my sig, you can see that the EZ is the only fueling mode made to my truck.

About two weeks ago, I started having a little stutter at take-off and quiet a bit of smoke, even at slight acceleration. I started watching my boost gage and noticed I was getting only 22# of boost at WOT. I moved the jumper on the EZ to all setting, including no jumper, and it made no difference on the smoke and I could feel the EZ kick in at 10#'s. I disconnected the EZ and the smoke stopped, and the boost will reach 20# at WOT. There still seems to be a slight stutter at take off.
After talking to a couple of pretty knowledgeable guys on here, I decided to take the MAP sensor out and take a look at it. While I was at Auto Zone having to go buy a 1 1/4 deep socket, I asked if they might have a MAP sensor for the truck. He looked it up and said they did. When he brought it out, it was nothing like what the EZ plugs into on the truck. It was a little black thinggy. I called Cummins and they called it a Boost Pressure Sensor.
Well, anyway, after a few skinned places and another trip to get a 5" extension, I finally got it out. It looked clean and I could see nothing down in there. I cleaned it out with Berrymans and WD40, dried it out and put it back on.
When I hooked everything back up, I reconnected the EZ. I took it for a test drive, and no change from the original symptoms.

Also, I changed the boost elbow and made sure there were not leaks in the inter-cooler, and have sent an email to Edge.

Any ideas?

 

Come on guys. I need to fix this so I can go fishing.

How long does it usually take for Edge to answer back?

 

When my first comp acted up on me I sent it in and had a brand new one on my doorstep in less than a week. No questions asked. Maybe the EZ itself is just messing up. I wish we could have tried my comp out on yours to see if that was the problem. Hope you get it figured out.

 

crobtex did you ever get this problem figured out and if you did what was it?? I have had the same thing only can't get much past 36 psi with my setup.

 

Yes, any updates?

I have been having low boost/power issues and finally pulled the EZ off just in case. No codes or anything. Fuel pressure is great - WOT 12#s.

My steps -

Check IAT
" " MAP

That is all I can think off right now, but boost is way off and I have no idea what is going on.

BTW, sure is hot here in our great state lately.

 

Check all the intercooler boots.

Check to make sure they are still attached firmly to the piping, and all clamps are good-n-tight.

Check to make sure there aren't any holes in the boots, even small holes will bleed boost.

You can also spray some soapy water on the intercooler to check for leaks there.

The truck is running much better.

Edge replace the EZ, and I replaced the map/boost sensor and the IAT sensor. I now have smoke when I want it and have had the boost up to 26 psi. The EZ replacement didn't fix the boost, so I guess it was the boost sensor. The IAT (evidently) helped the low in town power on the 100* days.

A couple of days ago, I loaded about 2800 lbs of hay is my steel stock trailer. The first four or five miles, it seemed to ask me, "What have you done?" After that it seemed to have figured it out, and off we went.

"BTW, sure is hot here in our great state lately." Darn sure has been. Try loading hay in the field at mid afternoon.

 

Thanks Phox,
I checked all the boots and all seemed well. I'll do the soapy water trick as soon as I get time.
