I have the ability to "fool" the map sensor into thinking that it is getting more or less boost than it actually is. Less boost sensed it fuels less and more boost sensed it fuels more. Here is my question/s: Which will actually save me more fuel for higher mpgs...less/more boost sensed? I want to say less boost sensed but will this cause the turbo to build boost slower and put too much load on the motor causing more fuel to be burned? Will making it sense more boost fuel more making the turbo build boost faster/quicker response to grades causing less bog thus less fueling? During my daily commute in o/d at 55mph I am running around 1350rpm and 0-10psi boost depending on the grade. Most grades during my comute I only make a max of 5-7psi.
