So my graph is putting me at around 30psi so if I am remembering correctly i need to subtract 14 for my alt. which leaves me around 16 max psi. That really isnt that good is it? I am stock no programmer just 4 in and 6637. I am thinking when it warms up I need to look for boost leaks???
I must say Tuglys mods to my graph makes it look better than the 50 50 5 settings.

Sounds fine to me. But then again, I think the local forum consensus is 35.3336 PSI of boost on a stock truck these days and anything less means you should put a road flare in the front seat and walk away.

Sorry about the crappy attitude.
I have a cold and I never, EVER get sick. I spent Saturday evening with two friends of mine at a sushi bar and they had their two kids with them.
This is why I don't have children. I can't tolerate having a stuffy nose and messed up voice. Dang petri dishes anyway.

Nope, I am not "parent material". I'm way too selfish and way too short-tempered for that crap. There are other (more important) reasons, but politics aren't allowed in the forums.

Cody's flair for putting things in perspective notwithstanding... nothing wrong with 16 on a stock truck. However, as the truck warmed up, it peaked at 17 PSI boost. You're there, but I'd go easy on a cold truck. I do the egg-under-the-pedal thing until Stinky's at full temp... I know how it feels to be asked to do anything more than drool and scratch before my first cup-o-jo.
On another note I just seen a f350 Platinum in person at our local dealer for the first time. That thing is nice, but at 66,5 I would not expect anything less.

Homework
There is a link in my signature that I frequently point to. As much as I enjoy sending stuff Clay's way, these guys were very clever to have such detailed diagnostics posted for free on their site. Here is the same information in two formats:The assignment? Hook up and watch your AE data with the above page for a reference. If you have issues, please share. If you don't have issues, you now know what to expect when things work... so you can spot the difference when they don't. If you don't have a scan tool, there is fantastic information in there that is usable by anybody with a 7.3L. There will be no quiz... just share time.

A fellow member has an issue with very anemic power.
In this member's case, his IPR was under 5% at idle... this is really low. I don't it get below 10%, except on tuned trucks with big nozzles... but I've never seen it this low and this is a stock truck. Why would the IPR be so low? I asked him to unplug, then plug in the ICP sensor and I attached the resulting graph so you could take a look at what's going on:
- The Injector control Pressure Regulator - IPR (Injector Control Pressure Duty Cycle on AE) is a "valve" that controls your Injector Control Pressure - ICP. Remember, the ICP is what pushes the fuel out of the injector, like air pressure pushes beer out of a keg.
- The ICP sensor tells the PCM what the pressure is, the PCM takes all the other sensor data and the tune decides if the ICP needs to raise, lower, or or stay pat. Once the tune makes a decision, the PCM tells the IPR what to do.
- The High Pressure Oil Pump responds to the IPR, and the ICP sensor measures the ICP from the pump to tell the PCM what effect the IPR command had.
- Unplug the ICP cable and the stock program sets the IPR to a level where it "expects" the ICP to reach 700 PSI. This allows the engine to run in the event of an ICP sensor failure, but the sauce is substantially subdued (low power when driving).

Will have to check ICP again. IPR and HPOP is pretty new. T500 and new International IPR went in less that a year ago.
Oh I have checked out your links TUG. A person needs a full day and then some though. Tends to get a bit overwhelming. I will keep at it though.
Matter of fact I did some runs and recorded some IPR info the other day just havent had a chance to look at it yet, and still dont know why I cant get AE to load properly on my desk top.
thanks again all

Rich, you said you had him unplug the ICP and then plug in. Is the "what happened" circle where he plugged in again? but the throttle starts coming up, then he plugs it in - that's probably not right. Where's the plug back in part on the graph?
