Don't I know it.

I bought my truck in 2001 and it was more or less bone stock with the exception of a couple of rusted out cherry bombs pointed out each side. Still had the original pie-plate wheel covers and everything. I got, on average, 10mpg. Now I've got the 35s, 5" lift, new intake, cam, headers, flowmaster 30 and 3" out the right rear, and I still get 10+ if I'm not flogging it everywhere. My last tank I got 11.2mpg all freeway. [8D]

I'd love to pick up a gear vendors overdrive, I just can't justify spending another $2300+ to get it.

 

OD will just make it worse, you need to re-gear down to 4:56's to get the rpm's back where they should be.

Check your plenum for a leak, look down the TB for oil on the bottom of the intake manifold. common problem with the rams and will hurt your gas milage

 

What TB upgrade?? something I miss?? I am new, over from Jeepsunlimited.com jsut got a 509. 98 Ram 4x4... seeing whats available for it..the Volant coldair with ram additionworth it?? or jsut get a drop infilter??

 

Are you talking to me? If so you're crazy. At 60mph I'm cruising at about 2800 rpm, 80 it's like 3400 or so. If I go another 10% higher in the rear end I'll be cruising at near 4000 rpm. [:@]


And my carb and intake manifold don't leak. It's all running great right now.

 

mine is stock 2001 quad cab w/off road package with 275-70-17 bfg all terrains i also got 4.10 gears out back (Stock w/ offroad). i drive with a egg straped to my boot and still average 10mpg. I have have 35k miles on it and am going to get new plugs put in hoping this will help.

 

thanks for some insight as to what works. i just got this truck and knew the milage was not all that great. (my brother had the same year and his 98 with the 360 did better). from what i have heard the hypertech is the way to go, good to know it lives up to the claims. like i said not many miles on this thing yet but it averages around 12-13 mpg. not bad for a truck but i know they can do a whole lot better. just wondering is the k&n fipk that much better than just going with a k&n filter? seems to me you would gain just a little by smoothing out the air flow.

not real sure what i will do as far as the exhaust goes. headers i am leary of ( spent way too much time fighting leaks before, gets old real fast.) or has someone actually built a set that will seal. a cat back system eliminates the restrictive muffler and tailpipe but does nothing for the restrictive y-pipe, am i wrong on this one? or do they actually help.

 

I'm using Hooker Competition headers, ceramic coated - 1 5/8" primary into 2 1/2" collector, and I fought leaks for quite some time. But this last time I went in to Napa and had them call their distributor and I picked up some graphite high performance gaskets that I swear are at least 3/8" thick each. They've got about a 50% crush to them (not that you'll be able to crush them that much). This time I just threw them on and screwed them down as tight as I could (with a little short wrench) and so far, no leaks. Even after taking the driver's side off to replace the starter, still no leaks even re-using the gasket. Sure, mine's an LA 360, but I'm sure either it's the same gasket for your Magnum, or they've got a gasket for it.

 

it's probably your dual exhaust that's killing you...no low end torque.

 

you must not have a 2nd gen ram then, sounds like it's '93 or older. add some details to your sig to let us know what you have.
