another question, if i change the negative multiplier in the Adder to Pulsewidth Multiplier would that increase the boost levels? I guess it would be more accurate to call it a subtractor to Pulsewidth Multiplier

The thing I was trying to get at is that there is no pulse width multiplication above the stock values until the EOT is above 22 degrees C. Factor in that the low boost fueling is WAY LESS than stock at less than about 5 PSI and you have an absolute turd until there is some boost or until there is some engine temperature. You know that the accelerator pedal is even really "doggy" in stock when cold....well, it's even worse with this program due to the low boost fueling that has been taken away. If the numbers were to represent a percentage, there would be points of 10% less fuel in the Fuel Sipper program for any given boost/RPM combination.
You can put zeros or positive numbers in the "adder" map. It's not going to hurt anything. The PCM will not pull fuel under high boost.
