Thanks Pam, yours will be here tomorrow.

 

Good for you! Nothing much different here - SSDD - same stuff, different day. Yes, I think Jim has been helping RP out quite a bit on TOTM lately.

 

Morning John.

 

I wish I knew why I get much better MPG if I fill up when I have at least a half tank. I topped off the tank last night, 10+ gallons and the average was over 1 1/2 mpg better than I get when I put in 20 gallons. It happens every time and there has to be an explanation. May have to do with air in the gas or more evaporation with more room in the tank, but I would like to hear the reason.

Your smart. Quit slacking and be productive and figure it out

Morning Dave... Blue... 255 miles so far at the half way mark for me... prolly can squeeze out a few more. Gained atleast 2 mpgs alone off this custom tune. After winterblend... looking like 20-21 for my average.

 

Nice. I just started getting 15.5 in town all of a sudden with my truck and the only thing that I can attribute the increase to is I am not hot rodding around with the truck.

 

Don't get too excited Grasshoppa, until you fill up and do the math.

Thanks for the link. I had forgotten that post that actually had a real explanation. It really is amazing how that works.

 

your welcome, i know ive explained it a few times on the forums about how EVAP works

 

I know the points when I got my 17.4 average... I am beating them by quite a few miles. I know Ill be almost at 19 this tank for sure

 

Yup... light foots make a huge difference... I can only imagine how I would do with dynatech headers and 2.5" true duals on the highway all tuned.

 

Wow slow day in here today.

 

everybody is either busy or is taking a nap with jim, even though dave says that jim hides the pillows
