me and my brother have been working on his truck for a week new trying to find the problem and we are lost he has a 99 f250 stroker and it has been smokeing black smoke like a train and has no power on the low end plus it is pulling negative boost when at low rpms .
the codes it is throwing all say it has too much fuel pressure so we did the ipr removal and cleaned it put it back in now it loads up when u get on it and goes to missing and puffin whiteish grey smoke out the smells like fuel any ideas on where 2 start ???
