2015年4月1日 · No traffic, reset mpg - 21 miles one way, 21 miles back. Just wanted to see what she could do if I was doing around a 1000 or so rpm, around 46 mph. Even had the A/C on! She stayed within a few tenths the entire way. Yes, it says 31.7 mpg. Been staying in the 19 - 23 mpg range since she was new (almost 15k on her now).

2017年3月29日 · 4wd, yes. Gears, 3.73. Rpm @ 55 1700. 7999 lbs with full tank. Not flat, 5-20 varied direction wind. You need to realize it takes me almost an entire week to drive 8-900 miles before I fill back up. Today is rainy, cold and windy.

2017年3月29日 · I'll give y'all a little bit of background first. I've been tuning engines for 8 years as a hobby, grew up on a farm wrenching on gas/diesel tractors and equipment for close to 22 years, went to an engineering university for 3 years, and worked for Delphi automotive systems in …

2009年5月13日 · Over a 50k stretch of a twice-monthly 700-mile roundtrip — running 1,725/rpm at 59-mph — I recorded a solid 24-mpg despite day or night, sunny or rainy, 4-seasons, empty or 1k in bed, and always crossing a major metro. Highs to 27.

2006年6月9日 · Mpg is so subjective im surprised theses threads even get started. I’m sorry, if you are “averaging” 28mpg in a 6.7 Cummins, your either feathering it unloaded with lots of highway driving, not using it as a truck or fooling yourself.

2017年7月13日 · I was about to buy some off the shelf tunes to get 1 mpg more of 13mpg,until i came across this thread! Aloha from Maui,Hawaii! 2004.5 ccsb 4x4, auto ,4.10,BBI's,ARP's,airdog,smarty jr,285-60-20,leveled,14 mpg,amsoil bypass.

2019年8月30日 · Geeze, pics can be easily faked. Take a pic of the zeroed trip meter, drive 200 miles then fill half way print the receipt showing gallons used wow only 4 gallons in 200 miles looks like 50 mpg! Hey, I'm an internet superstar!!!! The truth is a newer truck with a 6.7 and all the crap on it probably can't break 20 mpg. Also I have a lot invested in a better flowing head that will pull great ...

2023年3月4日 · However, mpg's dropped and it had me searching for the answer. I concluded the additional airflow was reducing the ignition delay (ID) and pushing the location of peak pressure (LPP) closer to TDC which in turn hurts mpg's, but power went up noticeably, Boost response was awesome, very fast for daily driving, good dialy performance.

2017年3月31日 · I know they're heavy, but with little change in speed, they should help overall. Do you know what rpm you were running? Thanks for your feedback!
