i clean the turbo,now no boost or overboost help
hi guys first i will start with what type of truck i have:
its a 2006 f350 4x4 dually king ranch with 156k miles
the truck has sct programmer with eco,tow,extreme,egr delete,oil cooler delete,head studs,k&n intake,5" straight exh, changed the diesel filters about 8k,oil change about 4k,
now for the problem about a week ago the turbo started to get stuck,either open or close(no boost or to much boost) i decide in take it off and clean it,and check any sensor that like to go bad like icp,ipr,ebp,map,ait, only the ait and the ebp where really dirty so i clean them and clean the ebp tube.
the turbo was really sooty but in real good shape(little to almost no pitting) i clean the turbo real good with a 1" scotch pad,lube averything and put it back together,(i did mark the turbo)i was watching a video in youtube where a guy took the oring in the back of the solenoid of the turbo and with a magnet he was moving the vanes in the turbo,but the vanes didnt move. so i took the clip of the back of the solenoid and clean eveything inside the solenoid ( i think i didnt put everything back the right way) anyways i put every thing back toghether, it started in the first try no leaks nothing bad,i get it out to text drive the truck and is boosting real quick and over boosting,with alot of turbo farts when i let go the pedal, i drove it today all day doing the same thing but i was no tring to go to hard so i wont brake anything, about 1 mile before i get to the shop and start check if a left some thing wrong the truck runs out of boost,no misses only black smoke but i get no boost, i pluged the scanner and do livedata to check for presures in the map,baro and ebp, this is what i get key on engine off baro 14.6 psi,map 14.6psi,ebp 37.9 psi,vret 5v,and this codes p0470,p0478,p1408,p0046,p0069 before i star taking everithing off the truck can some one help me dig. my truck? turbo solenoid bad? map bad?ebp?turbo?
