What is the most efficient way to reduce smoke? Leave it stock.

Poor (or less than highly efficient) combustion efficiency and the amount of fuel per amount of air are big contributors.

If your program is designed to give you a certain PW at a certain RPM/APP/ICP (obviously there is no map for this, but it all comes out in the wash ) then one fix is to command less PW (multiplier) at that certain RPM/APP/ICP.

Increasing ICP will result in less commanded PW (unless the PW map has been changed...not the PW multiplier map) because the PCM will account for a mass fuel desired difference with the higher ICP and automatically lower the PW.

The low boost fuel maps are a MFD limit. They limit the actual MFD desired to whatever the value is for a given MAP vs. RPM. If you were to lower the low boost fuel to say, "30" across the board, you'd get a total MFD of 30 and have a gutless pig.

Setting the LBF map to an acceptable range while driving like a normal person (it would take some trial and error) and only allowing higher MFD under really high boost conditions would help.
