2011 f-350 6.7 boost lag and smoke
I have a 2011 F-250 6.7 with a 2017 style KC stage 2 turbo. I have been trying to eliminate some boost lag and black smoke on take off and when trying to pass at freeway speeds. What have you guys had luck with to help spool a bigger turbo? I am new to diesel tuning, so still trying to learn as I go. Also is there a reason for when I change vein position at idle in Mono Turbo Mode - Upper Limit that it doesn't match up with what I have set it to? I have it set at 100% and it sits at 40ish. I started at 30% in the tune but it was showing 9 in a datalog. I ramped it up in increments in my tune, and every time the actual would go up. Just not in proportion to the tune.
