No Turbo at start up white fuel smell smoke!

Background on my vehicle:
Mods. on my "07" 6.0.
MBRP 4" exhaust turbo back.
K&N Air filter
Edge Evolution Programmer. Mostly left on max setting (4) but driven very carefully.
90,000 miles

Problem:
1.) For the past 6-9 months I have noticed a slight dip in power. I could have sworn it was after I updated my evolution.
2.) On cold start no boost for about 10 seconds and exhaust blows white. Exhaust smells like diesel not coolant. After around 10 seconds or so at around 2000-2500 RPM turbo comes on and smoke goes away, truck runs fine. Seems as if the turbo is sticking or something is telling it not to come on. Has happened may times in the last few months but is now more frequent. There have been a few instances where I could not get the turbo to engage and the only fix to the problem was to pull over to the side of the road and reprogram level 4 on the evolution.

Notes:
I run real nasty high sulfur Venezuelan diesel. Im in Costa Rica.
Not really a local mechanic to take to. Would to prefer to fix myself.
EGR has been cleaned and was dry and fairly clean. Before I bought vehicle I did a Ford history search and vehicle had never been into dealer for service.
No Check Engine light has ever came on.

Any help would be appreciated. Hoping to hear that I need to clean EGR and move on.

have you checked connections going to the turbo? if you barely blip the throttle (i'm talking minimal) does the turbo start working?

how cold is it where you are? my truck smokes for about 10 seconds in the morning in the winter if it drops below 30 or so at night.

I would scan for codes. Chances are the turbo is needing a good cleaning. Even if there are no codes, it doesn't mean the turbo doesn't need cleaned.

When I step on the throttle is when I get the white smoke 2000-2500 rpm. Seems as if something heats up to certain temperature and "snap" the turbo engages, smoke goes a way and truck runs nice. I was thinking maybe time to R/R the turbo. Im a little discourage because when I cleaned the EGR it really was not that dirty. Maybe the turbo is rusted a little? I drive the truck about 1-2 a week. Its about 85 degress here year around.

the worst thing to do with a 6.0 is to let it sit... clean the turbo without a doubt
