I have a 2006 F250 with the PS. I started to have some turbo issues, decided to do a full bulletproof job since it only has 68,000 miles and I want to keep it forever. Ordered a full kit from bulletproof diesel, a new turbo, an s&b intake, and an sct livewire ts+. Had the work done at a very reputable diesel shop (Scheid Diesel in Lafayette Indiana). They installed everything and called me to say the truck was very laggy. They spent a couple days with it, but couldn't figure it out. I have a very experienced PS tech near my house, so I took it to him. He has had it for a week and a half, and he can't figure anything out. He has all of the proper diagnostic tools and expertise. He did find the oil pressure was low, so he put on a new HPOP and nothing has changed. The truck idles fine, no codes, everything is reading within the proper parameters. I cannot hear the turbo at idle, and trying to accelerate this thing acts like it is pulling 20,000 lbs up a hill. Fuel mileage is in the toilet (I'm talking 9mpg highway). He has checked exhaust blockages, cleaned everything he can think of, fuel pressure is good, oil pressure is good, tuner is set back to stock, ecm got a factory re-flash, and nothing has changed. I'm desperate at this point, can anyone help?
