NO not at all... I have used mine up to 90MPH ... Not sure whats up with yours but Im sure its not the gears...johncode said:For those who have 4.56s. Did your cruise control stop working when you try to use it over 50 MPH?
I've only had them for a couple of days, I just expected a little more. My MPG comparison is based on my MPG after a fill-up and overhead reset before the gear swap and filling up at the gas station around the corner of the shop with the overhead reset after the swap. I was driving like a granny before and after the swap so I could compare, maybe it'll get betterAIR_RAM said:WHAT! You must be driving with your foot through the floor from every stop. There is no way you lost MPG unless you have been driving hard. As for it feeling like your 3.92 from 30MPH... LOL see if you got anyone in your HOOD with a HEMI with 3.92 and see how he/she stacks up... I bet they dont... and you will WALK them from 0 from 10MPH from 20MPH from 30MPH From 40MPH... ... Ok Perhaps is feels the same but it isnt! Have you taken her to the track yet?
SPEED SAFE, AIR RAM
Well, I just got back from a 100 mile highway trip and got 14.9 MPG :bawl:warp said:John, give it a chance, dont make us look bad down here
Take a cruise and calk the milage
I'm not making an overall gas mileage complaint. I would keep my truck if it got 10 MPG. I'm just wondering were this 4.56 magic is. There are a few posters saying your MPG gets better with 4.56s and its the best mod they ever did. I'm just relaying my results. I'll probably keep the gears, just a little disappointed with the results thus far.mitchgmace said:I think you should sell the truck and buy a ricer (KIA) perhaps. Those Ram trucks are way over rated. lol
