The most ive gotten with my 07 long box super cab 4x4 is 20.1 on a 1000 km long straight flat stretch in northern ontario. This road also has some serious hills before and after the flat stretch and the best way I've found to save fuel on them is to keep the cruise off and build up lots of speed going down and then bleed it off going up the next one, basically just plant your foot in one spot and let the speed do what it wants within reason. Obviously you dont want to be crawling up hills as this will defeat any gain in economy you might get, but gravity is free use all you can. 88Racing called this roller coastering in a reply to a post I had make a while back. I liked it and call it that all the time now.

I was also wondering how much pedal Longshot uses? I havent got the vac guage for mine yet and was thinking I might be able to use accelerator pedal position off the gryphon instead, the two should be directly proportional although not necessarily a linear change relative to one another. Or maybe just go by rpm outright while accelerating. Do you keep it under 1900 like Hampsterzone? I had been accelerating around 2000 but have started shooting for 2500 and I think I'm actually seeing an improvement. Its just an estimation of course, its way too hard to get an accurate fuel economy calc this time of year for me. But just going by what the instant economy is and for how long it stays that way for a low power acceleration vs a moderate power acceleration it looks like 2500 is working out better. I wish it would work best with the pedal to the floor, I'm kind of in love with the sound my new exhaust makes.

Good topic, Its always interesting to hear how many mpgs others are getting and what they are doing to get them.
