My 98 Dakota 4wd 5.2 5-speed rips. My son is a tech at the local Dodge dealership. We resynchronized the timing. I fixed the plenum leak and install back of cat Flowmaster exhaust. It only has one cat. Has great power and will climb most any hill in 5th gear. Also get around 20 mpg at 80 mph and around 25 mpg at 65 mph. Though the Dakota is about 800-1000 lbs less than a Ram.

I had a '98 QC 5 speed 4x4 with the 318 and it would give my '01 360 QC 4x4 auto a run for it's money. It ripped just like moparmarks '98 mentioned above. Just started running my '01 Reg Cab 5 speed 4x4 318 and it is definitely slower than the '98 and has almost no torque under 3000 like you are mentioning. I hooked my Torque app to it and the timing is showing anywhere from 23 to 31 degrees out on the highway at steady cruise. Well, that definitely can't be right. On the plus side, I guess it comes Turbocharger-ready from the factory. I'm thinking about finding a '98 computer to get around this death flash nonsense. My info on those "tuners" is that all they do is have a circuit in them interupting the coolant temperature that fools the factory computer into thinking the engine is cold and they run in closed-loop rich to make it feel like you have more power. You have "Turd" and 46re transmission close together, and you would be 100% correct on that: I found out just how much of a power-sucking turd the 727-based platform is when I got my first 318 a833od. It was like a night and day difference to any 318 automatic I previously owned.

Yes, the convertors are a plug in the system. I take all of mine out and usually pick up 1 to 2mpg. They struggle a lot less when in top gear and maintain cruise much easier.
Electric fan while you are at it, the trucks make less noise, and pick up a slight amount in the mpg department.

Ive had several, none seemed underpowered, Drive my 3.9 and then tell me your 318 is underpowered. I'll have to get a video of it's acceleration. It's hideous.

I recall some conversation years ago about modifying the crankshaft sensor (edit: for advancing the timing)............and just found it: Dakota Forum.......and an explanation of the origins of Death Flash: UTawesome Performance

I am considering removing the cat since I no longer have to go thru inspection due to its age. Is there any performance advantage to doing it? Ah, the childish advantage of blocking another Member's posts. No, leave it in, dummy.

I am considering removing the cat since I no longer have to go thru inspection due to its age. Is there any performance advantage to doing it? I don't think you'll gain anything. But, as old as it is, I doubt it's working at all anymore. We went through MANY in our 350,000 mile 318 Ramcharger. Always failing smog for NOx, every year or two, always the converter. Near the end we discovered those muffler shop cheapies were universal fit and crap. Finally got one from Walker, specific fit for the truck, lasted until we sold it in 2016.
