4.7 98 mph cut off

:p Yesterday I decided to call the dealer and I told them that I put bigger tires 18" on my truck and now the truck cuts off at 84-85 mph insted of 96 and he said sorry, but talked to another tech and he said that there are 3 settings on the computer for the different size wheels that come on the dakotas. so they could do that for me. boy I sure hope so as soon as I can. its that or the 350.00 ase chip.

Hey SSrage, I've got 225 40 18" tires. I don't know how to post pics, but you could go to www.severedties.com under chapters and pick nevada. another site is www.truckrun.net go to old shows pick forbbiden fantasy then go to the 3rd page.

Damn Sic! Thats tight!! But the real question is: Can you get it any lower? I'm not a fan of lowriders but yours takes the cake. Thats awesome man. Who did all the metal work and the shaving? Whoever it is from what I can tell is great. Raisin the floor of the bed was a great touch... course you had too with that style of drop but its still slick as hell. Or Jst2Sic in other words! :eek: :D

I did not know that the 4.7 had a 96 cut off. I have a durango, is that the same on that?? I put 20's with 245 40's on it. What is a ASE chip??

Thats kinda odd, I have 20s on my 02 Durango with the 4.7 with 275/45 tires on it, and ive had it to 105 mph without it cutting out.
No tire size mod had been done at that time. So go figure.

Ya I could not remember wether I have had above 85 or not. I don't thing so. I am fixing to order, the HO cams, hughes engines HO intake, and a throttle body, not sure which one yet. then later on when I can afford it I would like to get a supercharger for it.

Cuts out? Really? Man, I could have sworn I've had mine up around the 105 range a few times and never noticed any cutting out. I'll give it a try again this weekend. :D

Ummmm... I wouldn't say mine cut out at 98mph... it more like just died at 98mph. Then came back to life when the speed dropped below 95. It literally just nosed over and quit.

is the cut off at 98 maybee a two wheel drive thing? I have a 2002 4x4 with 4.7 5spd auto and I have been over 100 a few times once hitting almost 115 but backed off to prevent losing my tires or causing a big wreck.:huh:

my bro and i have almost identical trucks. his is auto mine is stick. both 2x4. his shuts down at 98 mph. mine shuts down at 114 mph. i heard it's due to his having a aluminum drive shaft and mine being made from steel. the alum. can't take the revs the steel one can. not balanced good enough or something like that

All I know is that the 4.7L with auto's are supposed to cut off at 98mph and the sticks around 115mph. I don't know why its this way but I read it in Truck Trend I think.

Yeppers.. and it sucks LARGE! first time I've heard the driveshaft explanation though.. makes a little sense.. more so than tire speed ratings.. which is false.

The ASE chip won't move the limit. A PCM flash such as the B&G, Leach or Kenne Bell are the only things at the moment that will alter it, to my understanding.

This is unfortuante for those of us that do some mods.. such as TB, CAI, HO intake, true duals, cams.. and decide to take a run at the track.. there is a pretty good chance we will hit the limiter before the end of the 1/4 mile. I'm not a racer.. but after my mods are done.. I do want to run it just out of curiousity sake. (and possible bragging rights :D )
