moneypit white smoke

[manalive37]

Hi guys. New to the site. I've got an 01 ford 450 xl with the 7.3 turbodiesel which is suppose to be the best known engine made lol. I bought the truck last year and it was maintenanced very poorly. So now it has all new fluids. New tires and brakes,filter, etc. The tank delaminated on me. So I replaced it with a new plastic 40 gallon one and new fuel pump. Flushed the lines and fuel bowl and replaced filter. I also found loose connection at hpop and it was leaking so I replaced hpop and during the process I found no nut on IPR. I put new one on there. It has a new garret turbo with the pedestal upgrade. So with all that said. I was driving it today with no load and when it got up to about 2500rpm it started to cut out. I have over 12 gallons of fuel in the truck with the extreme diesel additive added. I also have plenty of (nice halfway clean )synthetic oil in engine. When I pushed on the gas it started blowing white smoke and I couldnt accelerate above 1 grand on the tac. So I drained the fuel bowl and held it to the floor out in the driveway til it stopped blowing smoke and sounded normal. Now everytime I drive it white smoke pours out when I give it some juice and it still stutters. If you had to make a next step. What would it be? I did look for fuel leaks everywhere thinkin maybe I had a loose line allowing air in. I dont have a fuel pressure gauge other than my bullydog which I unplugged at first sign of trouble, I think it has adequate pressure. So Im scratchin my head and warming up my wallet lol as I get some advice from the pros. thanks in advance Don
