    I have no other trans issues ,everything works great other than at wot it tacks all the way to rev limit before it shifts. You have to lift in order to shift before it cuts out .

    The '02 5.9 gasser is pretty much the red-headed step child of the 3rd Gens. A 2nd Gen engine tranny combo with 3rd Gen frame/chassis/suspension, etc.

    The 5.9 is a pretty damn stout engine, basically designed in the late 1960s as the "LA" series of V8s that included the LA318 (5.2L), LA340 (5.6L) which I personally thought was the best of the three, and the LA360 (5.9L). This engine basically remained intact through the years save some technological upgrades like fuel injection.

    But being long in the tooth, the HP to displacement ratio is pretty low by modern standards making about 230 HP at the crank (185 RWHP) although due to it's displacement Torque numbers are pretty good at 330 lb/ft.

    Gas mileage has never been a strong suit, my '98 Regular Cab 5.9 4x4 after a 3" body lift and 2" level and 35" tires got about 9 MPG in overall use and if I didn't do much over 65 mph I could just nip 12 MPG on the highway. By comparison, my '04 Hemi is a QC, is about 1200 lbs heavier after mods, has roughly the same lift height and runs 35" tires also and I average close to 13 MPG in over-all use and usually see 16 MPG on the interstates with the cruise set on 70'ish.

    Due to the plenum issue that plagued this engine basically since the day that Chrysler ditched the carb and went to a throttle body design, the engine was pretty de-tuned at the factory (Google "Death Flash") and so benefits greatly from a tuner. Best gains I've ever seen on a non-diesel are obtainable with a tuner for this engine. Superchips can net you almost 50 HP and 50 TQ on this engine - but at a risk of blowing the plenum gasket (which can be fixed for good with an aftermarket kit like a Hughes).

    Re-gearing will also help this truck, but remember unlike the Hemi you don't have a 545rfe which essentially has two over-drive gears. So over-doing it will cause more MPG woes. I'd go no more than 4.10s unless tire size exceeds 35"...

    I've got the 02 also. I have some of the same feelings as you but you'll find out a few things along the way. I really wish i would have gotten the hemi. At the time i wanted a truck this caught my eye price fit i needed a vehicle NOW and got it. I love the truck and plan on keeping it. Most websites list things as per the 2500/3500 model specs which changed in 03. Everything that fits an 03 will fit an 02 1500. Get a tuner! I highly recommend and as stated above this engine sees the most gains out of one. Also do the plenum fix. As hammer said its a problem that if it hasnt hapened yet, give it time, it will happen. Other than that i think you'll find out its not that bad of a truck.

    Thanx for all the info guys. All that being said ,what tuner do you recommend? Here sc seems to be the fave while other places brag up the sct tuner . Are there big diffs? I kinda like the idea of sct being custom tunes compared to a sc canned tune but my tuner knowledge is very limited so suggestions from you guys is welcomed. What can i expect from either one of these products? I know the sct is available w/3 tunes for about $50 cheaper .

    superchips will suit you fine if you are not planning on alot of mods such as cam,heads,and things of that nature. if you are going to go crazy with mods get the sct. it will support everything you want to do. i learned this from experience.lol. i have had jet chip,superchips,hypertech, and now sct. i really liked the superchips before my mods out grew it.

    and your 5.9 without alot of mods wont keep up with the hemi. i have a hemi too. and bone stock it runs very well. and the 5.9 gets some pretty crappy fuel mileage. its the nature of the beast.

    hammer summed it up well.

    i agree with you 100%, looking at parts 03-08. and taking it easy unloaded getting 11 gets old. Once i am back to work i am planing on doing some mods such as intake and exhaust. I also agree with Turp do supporting mods before you chip.

    You can get a hemifever tuned SCT with 3 tunes for your truck which are basically canned tunes. Your real benefit with the SCT is it is able to have custom tunes if you get into cam swaps etc. The superchips works great for me. It really woke my truck up, but i have no actual experience with SCT to say which is better.

    Sean has a package for unlimited custom tunes if you go that far.
