NO GODFORSAKEN BOOST
Yeah im really pissed. on my way home from church tonight, my truck isnt giving me any boost.
When i started it i thought it sounded funny, when i accelerated it felt even funnier, felt like my 7.3, you floor it and it goes nowhere. both my boost gauges(stock, a.m.) are showing no boost, i stomp on it, climbes to about 1800 rpms, no boost, then jumps to 2500 with 9 pounds of boost. i pull over on the side of the road, restart the truck about 5 times, nothin, still not producing boost. so i take off again, im checking to see if its black smoking, my friend is behind me and im using his head lights, but no smoke. finally make it up to 65-70 mph, at that speed i normally see about 10 psi continuously, this time nothing. i get home, listen to the exhaust sounds like a non-turboed v-8, cant hear my turbo at, and usually its screaming. pop the hood, all the CAC boots are on and everything looks fine.
I am pretty po'd right now, so sorry for any grammar mistakes.
I know its going into limp mode, truck has never done this before, its been 2800 miles since i got the EGR deleted and this is the first problem i've had.
Is there anyway to reset the code(no cel) so i can at least drive to school tomorrow?
Also dont want hp tunes, because well like most 17 year olds i'll use em, to the best of their abilities

My boost shut down last night too, and I was thinking turbo, now I think the ficm has finally died. It was running fine, shut it down, got back in a few hours later, and it would hardly run. I'm thinking, no fuel, no boost. I couldn't get more than a pound out of it, floored, it wouldn't hardly accelerate, then I bumped the Edge up to race, and within a few seconds the boost hit and away it went. Could your problem be fuel...??
I'm just brushing up on the solder rerun for the ficm, and heading out to the shop to try it. Good luck!

Did John clean your turbo when he had it off?
I agree that it might be vgt solenoid or something along those lines.

that's correct exhaust back pressure sensor, it's located on the drivers side manifold on a bracket. It's about 1/2 way back on the engine. You may wanna try cleaning it w/carb cleaner. Also spray a good amount down the tube or take it off and clean it w/a pipe cleaner.
