well I have seen the light, I am going to buy a Dodge. Ive driven Fords for 30 years, and after some research decided to go with a Dodge and the Cummins. So my budget lead me to a 99 2500 Laramie short bed 4x. Automatic trans 140k on the Odom. It has a 4850lb front axle (looks like a dana 60) and a 6684? lb rear. Not sure but looks like a 70? Has 3:54 ratio. Pretty nice condition, never been modified, no chip, no lift, which is what I was looking for, (I plan to chip it myself). It does have an issue with the low speed sensor, or so says the owner. Speedo wont move till you get up to about 35mph and the cruise and auto door lock wont work. He claims the part is cheap but not sure if its the trans or the diff sensors. Was hoping for input. Ideas about the sensor issue, what to expect from these years and whether a chip is a good or bad idea, I really want to get max mileage and still keep the power. I have had a 91 F350 for ever that I had a ATS turbo put on and the injector pump turned up. It has a nice turbo whine and plenty of power but this Dodge stock seems to be quite a bit more. Thanks in advance for your thoughts

Sensor in question is on rear axle. Part reasonable price. Inspect wiring at left frame rail and rear axle spring hangar.

First thing you need is an aftermarket lift pump, and a set of gauges.

I got my rear wheel speed sensor from dodge for $35 and it took 10 minutes to replace. Your right on the axles being d60 and d70 and like pepsi said get a set of gauges, fuel pressure, egt, boost and tranny temp. These trucks need a constant 10 psi of fuel pressure for the injector pump to live so a new lift pump like airdog or fass is almost a must. For more power look into a edge comp if you like the looks of standard gauges or a edge juicewith attitude moniter if you like digital readouts. You can look in the classifieds at the top of the page for good deals on used chips.

if your adding more power you must upgrade the lift pump, or else you will run into problems, i don't care what the counterculture thinks, you need the fuel psi, ad that requires aftermarket pumps.

thank you for the info. So I looked at the Fass and the Air Dog. If I get it right, these are designed to replace the factory lift pump? They both look like they have a 12 volt motor and must be a vane style pump, has some kind of adjustable psi regulator? Is there any way to test the injector pump to check for potential damage? It looks like right off I would need to shell out 5 to 8 Franklins for the lift pump, and 3 for a chip, plus the gauges another 3. The pod kits all look like a 3 gauge set for trans egt and boost, didnt see fuel psi, any info on that?

talk to wally over at FTE Diesel, he is a good man and will set you up.


I got my Diprocols (gauges), wiring harness, and pod from him, plus the fass, he knows alot and his customer service is number one.

Im with pepsi again, Wally is a good guy with the best prices and is a site sponsor. Tell him you dont want an isolator for your fuel pressure gauge but instead you will use a needle valve because it will save ya $100. I have my fuel pressure gauge on the steering column.
