New Tunes

My daily drive to work is 60mi one way from the gas station. Sometimes in the morning I'll fill up my truck with the same pump at the same fill rate (first catch on the gas pump so it doesnt foam as much) and I top it off to the even dollar amount. I drove to and from work (120mi round trip) and topped off my truck again at the same pump with the same pumping rate...to get the same amount of fuel in there...ideally. I drive with the 140hp tune 95% of the time and my hand calculation was 16.9mpg which was the same as the OHD

ChrisCNC, is your truck 4x4 or 2x4?

yours is the first ive seen with the ohd being right on... my gasser dodge is close but always off by about .3 or .4 mpg. ive got about 200 miles on this tank so far with the new php tunes in the 80hp dd mode so about another day or so and ill hit 350 again and go to the pump and see. so far the over head display is reading 18.7 mpg. it would be nice if its close to being on, that would be over 2 mpg difference over stock, but im not holding my breath, im thinkin probly only gettin 17mpg just judging on where the fuel needle is right now as compared to usuall.

alrght just filled up again. my overhead display was reading that i averaged 18.3 mpg. my hand calculated mpg is 17.5. so it is off by a little more than half a mpg. not to bad. and that is also a 1 mpg improvment over stock. that was mostly all in the 65hp dd tune. this tank will be all in the 80hp dd tune and will also be a 1800 mile round trip from northern michigan to memphis tn. not towing anything and probly oing to average 70 mph so we'll see...

Mine does best if I keep the rpm under 2000, that's about 68 mph in my truck
