Well ran the last part of my trip with no Jet Module installed, mileage went to 17.8 mpg. The driving conditions and terrain were just about identical as the first trip, just in reverse order.
Did notice that the Module did have some tracking on the ground pin, was most likely causing the battery light issue.
Truck ran great, idled great and over all ran smoother with the Jet Module removed. It's For Sale 1st hundred gets it if anyone is interested....
