Just put a factory ATS turbo on my 86 6.9 with c6, 3.54 diff, 3" exhaust, running waste veg oil diesel blend.
I turned up the IP fuel screw almost a full turn.
Gray haze at WOT. No coal rolling.
Still not getting much better than 15mpg.
If the fuel screw is turned up too much, could I be wasting fuel, even though it's not smoking?
I typically drive 90-105km/h on the highway (60mph).
Would love to see closer to 20mpg.
