Here's the deal. I have a 2003 F350 with the 6.0. Bone stock as far as performance mods other than I just installed a brand new Powermax Turbo recently. Problem I'm having is that the VGT duty cycle only goes from 60 at idle to 39 at wide open throttle. I'm reading this with a Scangauge 2 while driving. I know the duty cycle should be about 85 at idle. The truck runs like an absolute dog off the line. Anyone have any ideas as to why this is happening? Any suggestions would be greatly appreciated.
