hello, first time on here. Decided to join Bc I’m at a loss and frustrated. I bought my ram with 170,000 miles, with the intent to rebuild. I haven’t had the luxury of having power since I bought this truck 4 years ago. Runs good on flat ground and barely keeps up speed going up to the mountains( I live in Denver). When towing my camper up for hunting season. She will only do about 25 miles per hour climbing. List of stuff I’ve done.
New cat, new fuel pump, new tune up, tranny rebuilt 1.5 years ago, new timing chain and gears, new water pump, new alternator, new power steering pump, new steering box, new ball joints, new track bar, new tie rods, new rear and front brakes, new front hubs and bearings, new lift and suspension, this is only a portion of what I’ve replaced. I only mention more than what would affect power to show how much I’m into this truck. I can’t figure out why she’s got no power!!!! I think it might be the tranny. Which I’m going to get a monster transmission. ( any thoughts on monster transmissions) any help or thoughts on power loss??

Horror stories!! Ok good to know any recommend tranny’s. Yep replaced the o2 censors when I replaced the whole exhaust. She’s a 99 doge ram 1500, with the 5.2. Haven’t replaced the plenum gasket yet. I stuck my magnet down and it’s not aluminum. Was able to see in and there’s a tiny tiny bit of oil. Would that affect up hill power??

Maybe it’s bc the motor has 220,000 miles on her?? I’m eventually going to replace the motor as well. As far as gears I’m not sure yet. Trailer is a pop up weighs 2800 I’m going to check tire size here shortly..

thanks I will do the compression test.

I can see them as a smaller motor, but if I’m not mistaken the 5.7 doesn’t push that much more horsepower. Hmm death flash I’m going to have to look into that and see what it is, my luck my trucks got it, I’m running 285 tires now and about to go to 33” I just lifted it 3”. I also heard I might have to change the gears as well.
