I'm having 'my' transmission replaced with an ATS Stage 1 trannie and t/convertor package at the local Ford garage. While that's being done, it would be an easy task to replace the turbo. I know that the 2015 F350 will fit and is a bigger, more responsive turbo, but does anyone know if the 2017 will work? I ask about 2017, because that's the year that Ford increased the towing capability from 15k pounds to ~21k, so the 2017's should have a better turbo. If anyone can add input for this, I'd appreciate it.
