Well here is the first set of numbers I could grab today on the way home from work. I am not real pleased with the Boost numbers. Everything else you guys will have to tell me about as far as parameters and such. Enjoy!
Boost-10 average 13 best
IPR- 12.1% Idling 34.9% WOT
ICP- 700 psi idling, 2590 WOT, 1540 cruising at 65
Trans Temp- 145 degrees at OT
Injector Pulse Width - 1.22 to 1.30 ( have no idea what this is)
EOT- 190 idling, 203 running hard, 195 cruising
That's it for now. I'll have more info when I take it in and download some other stuff. Let me know what you guys think! Thanks.
Check for boost leaks at spyder, boots, and plenums Make sure you don't have any exhaust leaks pre turbo
Thanks Mike. I'll take a look tomorrow and see what I find. I poked a little with a flashlight tonight when I got home but didn't see anything obvious...yet.
Your icp at idle is higher than mine, I'm about 540 or 550. Could be the lighter oil I suppose. I've been using that torque thing. It's pretty sweet but I gotta get a way to mount my tablet.

Thomas, is that good or bad? Edge came with a really nice mount. It should for the money! I am most concerned with the boost. Now I get to start hunting down leaks. My IPR seems to be good too based on what others have seen. I think I am missing the Oring between the plenum and the turbo. That might be my bigger problem. We'll see soon enough!
Bryon, 10 - 13 PSI boost is about average for E40D. It's hard to get the boost numbers up with an automatic unless working the truck hard, pulling heavy or lack of a programmer.
ICP at idle sounds about right for a cali-truck, if that's what you have. Federal models idle around 600 PSI.
Injector pulse width 1.1 - 1.6 is measured in ms ( 1/1000) of a second. It is the amount of time the injectors are open. If IPW remains constant and ICP increases then more fuel is delivered. If IPW increases and ICP remains constant then more fuel is delivered. They both work together though to deliver required fuel. IPW is one of the more boring parameter to watch.
Try this, watch IPW while climbing a hill. On the down side of the hill let off the peddle (coast). IPW goes down to 0.4 - 0.6 ms. The PCM is telling the IDM not to fire the injectors, but keeping in sync with each other, and that is why the engine is so quiet.
I would think yours would be better. But I'm running synthetic 5-40 and you are running 10-30 aren't you?
Yeah Thomas, running Rotella Dino 10w-30. It's helped a bit with mileage and startups. The 7.3 seems to like it. Rotella also makes the synthetic blend in the same weight, but it's $4 more a gallon so I am sticking with Dino. I do changes every 5k miles so it doesn't make sense for me to run synthetic anyways.

Enjoy your new toy ...
Jim, thanks so much for he clarification! That helps me a lot. I was kind of dreading trying to find a leak that I don't really have time to look for at the moment. My first thought was that my new uppies were leaking! I am glad that isn't the case. What kind of numbers do you see with your setup?
Also, thanks for the education on the IPW. I kinda wondered what that was all about. Is there anything I can do to increase boost short of a programmer? I wondered about the wastegate or something like that. If I can't, I'll live with it. It's not a huge deal to me as I long as I know it's normal.
I still have to get the probe for the EGT. I'll be doing that this week. I am pretty stoked I have so many parameters without the pillar and twice the cost!
Hmmm, mine sounds low then, it definatly runs better with the new o-rings, but I'm still not satisfied with the idle, I have a feeling with all the miles, somthing is worn out I'm sure.
The 97 f250 auto would make 17 psi with no leaks on WOT run with out a chip
Yeah my boost is definatly good then, the gauge says 25-27 WOT with the chip turned up. I'm more concerned with the ICP at idle, its always had kinda a lopey idle since I've had it.
To the OP, Byron it sounds like except the boost your truck is otherwise pretty healthy!

you must have upgraded injectors then..?
