Pentastar motor

The newer they get the more complicated they get. Today there are a group of processors all programmed to work together producing a balance of performance and mpg.
Engine processor, trans processor,anti-lock processor all matched programs.
So even if you moved 100% of this stuff to your a-body, from fuel delivery to wheel speed sensors, to gauges, the change in the vehicle weight would change up the way it performs. These processors do make adjustments for increased loads like trailer towing.
I'll have to ask my brother if this goes both ways, Would a 1/2 ton lighter than base load make it crazy ?
