Thats not too shabby at all. Anyone ever try the fitch fuel catalist? It got a great review on the powerblock a while back.

Have you upgraded your tranny cooler? When I had my f150, I installed a rv tranny cooler and a electric pusher fan that really pushed some air. I wasnt running any guages so IDK exact temp numbers but the tranny seemed to like me more after long drives while hauling.

Just makeing it easier for your truck to breathe is the main thing. Better flowing and colder intake air and cooler less restricted exhaust are the main things. I just put a cfm+ intake elbow on my rig and that alone made a noticeable difference. When time and money permits a good enclosed cold air kit, intercooler, exhaust, better fuel filters, and whatever else I see thats shiny. jk on the last one.

I was just curious to see what products were actually doing what they claim for our trucks. Its always good to ask around and do your homework before dropping a wad of cash on something.

 

Best I can get is about 19mpg if I follow the speed limts. But I have 35's and I keep the Smarty TNT up around SW7 all the time.

 

Keep it stock and do a air flow up grade to the engen.That way your truck will live a longe life. Do not use a K&M air filter they let in to much fine dust.One thing you should do is a EGT and a boost gauges The EGT will keep you from getting it to hot when in a hard or longe pull 1350 is all you went it to get. SW IN == good luck ==

 

i get 17.3 mpg avg between city and highway, if i drive only city its about 16.8mpg highway only is round 18.5, last weekend i pulled the 40ft gooseneck with a sameri and 2 atvs at 70mph and was getting 14mpg, my truck is completly stock.

 

the best iv gotten when my truck was completely stock was around 15 empty and 12 if im lucky when loaded but that was when it only had 40,000 miles on it..... i put a bullydog triple dog gt on it and straight piped it and now its gettin around 21-22mpg which is good for a dually i guess

 

from my guestimated mileage, my odometer gears broke, i am getting 17mpg with locked 4.10 gears, 37" tires, stock 727 and a race built 12mm ve.

 

what size rear gears do you have??

 

okay i did the calculation using my gps, i got 17.88 mpg and i did a lot of hot rodding around seeing as i just put the 4.10 gears in. thats on a stock(dubbed the high stall) torque converter with a non o/d trans. id say thats pretty good. suprised me at least

 

The biggest gains in mileage that I saw was when I installed the free spin kit and a cam from Greg Hogue I'm heavy on the foot and I'm seeing 22-25 the old lady gets somewhere around thirty she says...
