SSplaytoy Posted January 5, 2010 Report Share Posted January 5, 2010 Oh hell, if I hammer down WOT it drops to 1-2 mpg... Anytime I accelerate it's usually between 5-8 mpg, even gradual acceleration on flat ground. When I had the radix, mine used to read 0.0 or 0.1 Quote Link to comment Share on other sites More sharing options...

BlueAKSSS Posted January 5, 2010 Report Share Posted January 5, 2010 In the summer I was getting 13 city and 15-16 highway but its gone way down now 11-12.5 mpg probably because of winter gas I guess.... Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted January 5, 2010 Report Share Posted January 5, 2010 lol more like 9 Dan Yeah 9mpg, here were the variables for that figure......400lbs of winter sand in the bed, snow covered roads(very slow driving), and a sh*t load of extended idle time(remote starter to defrost/unfreeze truck). Thank god I only saw that reading once. Quote Link to comment Share on other sites More sharing options...

SuperStock Posted January 6, 2010 Report Share Posted January 6, 2010 It dosen't matter where I go or how I drive I get between 7-11. Maybe I need a supercharger to get better mpg haha. Quote Link to comment Share on other sites More sharing options...

Krambo Posted January 6, 2010 Report Share Posted January 6, 2010 With my converter locked going 65MPH on the interstate, I got 14MPG on a long trip (140 miles). This is not using the DIC as I feel it is inaccurate now that I am no where near stock. I topped it off and divided the miles into the gallons. Around town...forget it man. I'll bet on 8-10MPG...keep in mind this is a heavy breathing 408 not intended for gas mileage at all. My old Radix set-up got a nice 17-18 on the highway and 11-13 in town. Not bad for what it was.

[email protected] Posted January 6, 2010 Author Report Share Posted January 6, 2010 Yeah idk. I thought my mods were all supposed to help MPG, even if only a little. I've never seen anything past maybe 15-16 MPG, and that's only if i keep it pegged at like 65 or something (5-10 under speed limit? I don't think so...)

misterp Posted January 7, 2010 Report Share Posted January 7, 2010 Seriously? How do you get 15-18 around town? My truck has never seen 15 even on the highway... The only way you get really good MPG is if you run 100% gasoline and your tune is optimized both in timing and AFR for it. If you notice a lot of the better MPG trucks are with Charlie Wheatley's tune. Coincidence??? Mr. P. Quote Link to comment Share on other sites More sharing options...
