I'm throwing a lot of black smoke as the motor is spinning and getting up to speed. It throws extreme amounts when I'm pulling a trailer and getting on the freeway at anything above 3,000 ft altitude or so. It gets worse as I go higher and slightly better as I go lower. I have to shift the E4OD into second just so I don't smoke out anyone behind me. Timing is set around 8° to 8.5°. Max PSI is around 9.I thinking about turning down the moose Jr a flat or two and bumping up the boost a pound or so.
