Over the winter I built an HE351ve with 64mm compressor and 64x70mm 10 blade turbine to swap out for my 60mm WH1C over s475. I also swapped my used Scheid lightning 5x18 injectors to a used pair of 5x16s built by Will before PDD was really going. I was trying to clean up idle haze for the cruise nights I go to in the summer. Truck seemed to run great; super quick spool, EGTs in check, normal amount of smoke, and boost was down to 65 from 80-85 (which was expected with the smaller injector).
Ever since I built this truck I would have a thick white haze cloud behind me on the way to work but then would not be there the next day. I attributed it to a failing 160 pump that had been racked and abused. Over a couple months of running my new setup, these days started to get more and more common until the truck always hazed a white cloud, cruising egts would be 1000 on flat ground and 1300 cruising up a little hill. I took the truck to the track the other day and ran a lousy 12.7 compared to my 11.8 last year with my previous setup. I figured the pump must have just gone completely out as I also developed a missfire.
So now over the last week I swapped out an unmolested, low mile 180 pump. I added my 4k gsk, 191 DVs, and my tuned AFC, fixed a couple exhaust leaks, then put everything back together at the same 23* timing (pin timed and then advanced 10* on the balancer). Off idle throttle response is much better, engine runs WAY smoother, and there is definitely more fuel available. BUT I'm still getting the same EGTs, cruising white cloud, and boost maxes at 60psi. It feels lazy from 10-40psi of boost too, where before I noticed the consistent white cloud I would have the ability to just slam the boost gauge over as soon as I got to about 15psi (even with the new turbo and injector setup).
Sorry for the long winded explanation, but hopefully someone could help me figure out what is going on.
