I have recently been getting really bad MPG. I run a 75HP tune and usually stay out of it hard. Truck has intake and exhaust along with chip and gauges. I have been reading about the EBPS being a culprit?
02 Crew Cab. TS Chip. DIY 6637. 4" Straight pipe. Triple gauge pillar. Boost fooler. Regulated return & lift pump on the way
By the way Mine is hand calculated, and when fueling I fill slow so that I can get it full to the neck of fill tube so that I know I am filling to the same point each time. The way diesel foams, if you don't you don't get accurate readings.
