I have a 98 dodge 4x4 1/2 ton quad cab. I have a 5.2 with a automatic,4.56 gears and 35s on it. I have a power programmer and a k@n filtr . and it still seems underpowered. I have a 2003 with a 4.7 syock and it will dust it . any suggestions

 

Maybe clogged cat?
Intake plennum gasket???

I have 99 ram 5.2 only mod being the hypertech, stock tires stock gears (3.55)
Ive raced a 4.7 durango and I won... I dont think the ram and the durango would be far off.

 

4.56s and 35s with the hypertech, you must have some deeper issues bro...id deffinantly check the cat and plenum, im leanin more towards the cat though

 

I hear a rattling sound from the cat when idling. I had flows put on it dec and the noise has got worse . Maybe thats it. Can i cut it out without setting an engine light?

 

some of us get lucky and can gut the cat without the CE light coming on...my CE light came on when the cat completely clogged up. its a hit or miss thing. but if its rattling, its bad, go ahead and gut it and see if you get your power back, it needs to be replaced anyway

 

Ill try that first. She needs a waterpump anyways so i will do that why she is down. another question i see everyone talking about a 180 thermostat thermostat. But I got a friend with a 99 with a360 who tells me i need a 160 any suggestions

 

Don't listen to your "friend" whosaid you need a 160.....[sm=badidea.gif] unless,

you want to do the job again after the MIL comes on
just a suggestion

 

CAT, CAT, CAT!! I had the same issue with my 98 and once I had the CAT changed it was like a completely different truck! A plugged up CAT eats your power like you cannot believe, and our Dodge trucks are famous for it!

 

Went today and had cat . changed out. Thanks that seemed to make it it alot more peppy. everything was broke up inside
