There is a fix for the condensation build up in the intercooler!

I'm at 5000ft in Albuquerque, NM.
And I don't think our trucks are different at all, I think the positioning of the measurement relative to venting explains the difference.
I'm fairly confident I could hook up an analog boost gauge to your truck (the nipple 8" off the passenger side turbo) and your turbos will be spooled to 2psi on the highway as well.
I don't think the pressure drop from the CAC could even be close to 5 psi that is insane high pressure drop for a CAC like 10x any other CAC I have ever worked with.
I would like to see the post CAC psi on your truck but pre throttle blade

If there is an analog hookup pre-throttle blade (any 1/4" hose where I can 'T' it in) then I can do that.
I'm actually trying to put together a 3-gauge pod that measures the boost along the intake stream with 3 identical gauges, but I hate feeding the tangly mess through the firewalls and dash so I keep procrastinating.

I took my 2011 F-150 Supercab 4X4 with EcoBoost engine in for a oil change today.I also mentioned that on hills in 6th gear at about 1,200 rpm it had a miss fire.When i was told the truck was ready and paid they said they also ordered a new intercooler TSB 12-10-19 and deflector.I've never had it cut out on me or a Check Engine Light do you guys think the intercooler was the cause of the miss fire?
Thanks Mark.

My stock EB F-150 while cruising the highway has the turbos pressurizing the pre-intercooler pipe by 2psi at 65mph in 6th gear.
http://www.youtube.com/watch?v=ApORpL0p96U
Cruise control on - showing boost pre-intercooler (note: this is not the pressure within the intake manifold, this only shows the turbo spool on the highway).
My right foot can be seen in the lower left of the video - i.e. all of the inputs are using the cruise control buttons on the steering controls.
The boost gauge shows 0psi when the truck is off (so it is 'calibrated' enough to demonstrate that anything over 0 is 'boost')
Order:
at the start I am cruising at 65mph and you see 2 psi
you see 5 psi when I hit the 'accel' button a few times to get up to 70mph.
you then see it drop down to 0 as I hit the 'coast' button, back down to 65.
you then see it settle into 2 psi again when I hit the 'resume' button. This is what I typically see on a straight, flat highway.
The video ends with me hitting the 'cancel' button and the psi drops to 0 again.
The reason I used 'resume', 'accel', 'coast', 'resume', and 'cancel' is to show that the boost gauge is not stationary in any position, and to show that it is above 0 (by proving it goes down to 0 when I idle it with 'coast' or 'cancel'). If there's anything anyone wants to see done with this, I can take vids of whatever.
The turbos in my EB F-150 are showing 2 psi most of the time at 65mph. The manifold pressure is a different story.
But goes to show that these trucks are not 'idling' down the highway. Drag causes a fair amount of load even just loping along on a flat road. Enough so that I would average 2psi all the way across the midwestern states.
Also remember that mine gets ~24-26mpg highway in the summer (good mpgs) and does NOT have the condensation problem.
So I'm tempted to believe that there being an almost constant boost pressure in my CAC on the highway may be preventing condensation.
Perhaps if the waste gates are overactive on some other peoples' trucks, there is nearly 'idle' air in the CAC on the highway.
From what I'm seeing here, I would rather that the turbos be left to spool and the vent valves do the work of relieving pressure pre-throttle plate than to allow the waste gates to leave the air 'idle' for long periods of time in the CAC.
All I know is what the gauges tell me tho... and that I like the way my EB runs.

And also, the pressure drop on this CAC is going to be really low... it is a pretty big core...

Again I have never once had the shudder loss of power or anything else even in monsoon season.
I have 25k miles put on in 10 months

Geno51, were you using stock programing in the picture or were you running your SCT 91 tune? Maybe it is the tune you are running that makes the difference. Mine is a May 14, 2012 build without any of the TSB reprogramming installed.
I checked again today and at 70 mph I am running somewhere between 4 lb of boost and 2 lb of vacuum. I went on some deserted roads and slowed to 45mph and still didn't have that much vacuum. At 40 I did have more vacuum. than you do at 70mph. It would be interesting to know if the TSB's change the boost characteristics. Wish there were some lurkers from Ford, to confirm if the TSB's change the boost maps. Without the constant level of low boost my truck shows, condensation would probably not be a problem.
