Power Loss and Surging Issue. HELP!!!

I am going to try and be as detailed as possible with this issue. I have already started the trial and error/ process of elimination repair solution. This has been happening for about 8 months now.

What it is doing:
-Cranks a long time before it will start (5-8 seconds roughly) whether first start or 10th of the day.
-I am going to school on the sea coast and the truck runs fine in the lower elevations. When i am at home (much higher elevation) the truck surges around 50-60 mph and the turbo wont boost it just bucks and surges/ cuts in and out and looses power. If i stomp it to the floor it will come out of it.
-With the SCT turned on it has good power, If i turn the SCT off it couldn't get out of its own way.

What I have done:
-Replaced EBP sensor twice and the EBP sensor tube.
-Head Gaskets and studs.
-Cleaned turbo and had examined by three different mechanics.
-Has an EGR delete
-Matt Robinson's tunes erase the EGR trouble codes.
-HPOP was replaced two years ago
-Ordered a new MAP sensor haven't installed it yet though

I am just completely at loss as to what is going on here and getting really frustrated, any help is greatly appreciated!

You need to check your batteries weak or bad batteries will kill the FICM this will give a bad rough idle at startup because the voltage is to low must be 45v or higher if under 45v you will be killing your injectors.
The price of a new ficm around $1100 or you can have your rebuilt at BPD Repair Ford FICM Module for $300
or--- FICM Repair.com - Your Source for FICM Repair My choice

Testing the FICM
You need the Edge CTS this will tell you most everything you need for your truck plus it will show voltage to the FICM every 6.0 needs a good set of gauges.
