Just got the truck up to speed the other day playing with a Durango on the Interstate, He couldn't keep up but the truck shut down at about 115mph-120mph, I thought the Jet Stage 2 would take care of the limiter but I guess not, any way to get rid of it or set it at a higher point. I believe this can be done with hypertech's programmer but they don't make one for the 4.7L yet....any help would be great..

Public Safety Officer???? I know you meant the track instead of the interstate b/c that would be illegal.
BTW, I believe you were limited to 95 mph prior to the JET II.

The Jet is supposed to raise the limiter from 98 to 115. I only know of one that actually removes it: Marty (KRC Performance) - Custom PCM Flash.

I don't know what you guys are talking about. I've had my 4.7 up to 110, and I would have gone faster, but I had to slow down for some cars. That's without a chip to raise the speed limiter.

Again...different vehicles of the same make/model will perform differently. That's why some are slower and others are faster...with the same engine/trans/options. The speed limiter is supposed to be there though. (Mine is supposed to have a rev-limiter and speed limiter built into the program of the PCM as well. Have to run the MSD rev-limiter at 5500 and have had the truck at 115 with room to go as well. Don't know why...but others with the same make/model have hit the rev-limiter.)

Correct me if I'm wrong...the better the tires[high speed rated]the faster the limiter will let you go.I called Chrysler tech line,and ask how fast a Dakota will go be for the limiter would shut down,they said 95.People will tell you that they have gone 110+,I bet there have the PREMUM tires.My truck is a SLT + and has PREMUM high way tires,I don't know what mine will do,but I think it well do about 145.

I had my '93 at 122MPH. I'm not sure if that was top speed or limited. I know somoene who had a firebird and their limiter cut the fuel to the engine and the trans ran down the speed. In my case, it ran smooth at a steady 122 just wouldnt go any faster. I tried it several times and pushed it for about a minute or two with no avail.

Take it out on I-81 in south west Virginia. Lots of straights. I'm sure it doesnt compete with whats in the midwest though but living in New Jersey, I dont get too many opportunities to push it to the limit. I have 235/70/15's. The newer ones are a little more aerodynamic. I also found 3rd gear tachs out at exactly 100 MPH with a 350 rear.

OK. the 4.7 i know cuts off at 95, so your jet chip raised it to 115. 115 is the limiter on the 5.9 RT and boy does it suck. i have so much more throttle to go. There is a performance chip that will take it off. do some research

Bernd,
Do you know what the website for KRC Performance is or if they have a telephone number. I would love to get this truck up to speed, before it shut down at 115, I was only pulling like 3000 RPM's which gives me a 135mph-140mph feel maybe faster what do you think??

Bob don't be sad,remember how quick you get to 95 mph,thats more important than going faster than 95 mph.Plus it is only a computer thing not a problem with the engine.You can still beat 90% of the street trucks you meet without going near that speed,plus they probably have limiters also!!

I dont know about you guys but a couple of weeks ago when I got my 93 318ci 4x4 Dakota up to 120mph there was so much noise/bed turbulance, I thought the damn truck was gonna fall apart right then and there. I guess I should consider myself lucky that my truck probably could have gone faster if there was no traffic. Now I dont feel as bad losing to my dads 99 silverado knowing that once it hits 99mph its good night for him. That speed limiter thing really sucks!

Hey Russ, I dont know what your talking about when you say his truck could beat 90% of the street trucks ou there. Your telling me a stock Dakota w/318ci 4x4 could smoke a stock Siverado w/350ci Z71? It just cant be! I got a stock Dakota 4x4 w/318ci and I cant beat 50% of the street trucks out there. Maybe I should learn how to race, huh?

Ugh...went out drinkin with the neighbors last night...again. Head doesn't hurt though.
On the PCM and Fuel question, you "can" run regular unleaded but will have to add a bottle of your favorite octane booster with the Mopar PCM. The good octane boosters run about $8 - $12 (NOS, 104, ProBlend) which will actually raise your cost for fuel.
Example: (Using our TX fuel prices in my area)
Regular Unleaded ($1.18/ga * 20 Gallons): $23.60
Extra Unleaded ($1.25/ga * 20 Gallons): $25.00
Super Unleaded ($1.38/ga * 20 Gallons): $27.60
Add $5.00 (average for a decent octane booster) and the Regular Unleaded now costs slightly more than running Super Unleaded).

Here in Northeast New Jersey prices are approx $1.40 for regular and $1.55 for super. I never even pay attention to the midgrade. The prices may be higher here because in texas youre right at the source and youre allowed by law to pump gas yourself. Here it is illegal.

My 2000 4.7 reg. cab ran to 115 before shutting down. The only embarassment I had was on the interstate coming from New Orleans I was running a late model Mustang GT. He couldn't think about keeping up, that is until my limiter shut down and he passed me!! By the way I (was) running a basically stock truck with dual flowmasters, K&N filter, 3.90 gears, and a cowl induction hood. Tires were stock Goodyears 245/65/15's. All that is gane now since I totaled it last weekend on the side of a Ford Aerostar. Dumbass from Kentucky failed to yield at a light. I guess he thought he actually had a chance to beat me in the turning lane!! I never saw him until he darted in front of me and an 18-wheeler. I hit him at about 45 mph. I drove the truck 72 miles home and to the body shop and they still totaled it!!!
