About the lean burn module - It is nothing more than components from Radio Shack with a switch that interrupts and modifys the MAF signals to the ECM. This will allow me to cruise around 18:1 AFRs and stitometric (14.7:1) when accelerating or higher loads are needed such as hills.
Eventually, I will be tuning to run upwards of 35:1 AFRs, thanks to pgfpro
