hmm sell it and get a 4.0L cause from my exp 3.0L have no power.. i have a friend with a 3.0L 2wd.. and yeah it had no ballzzz to it at all..
but i suppose you should just look into increasing flow and having your tranny looked at..
i have a 5speed 4.0 and i can tow anything.. i do it all winter towing people out of ditches.. people are amazed my truck can pull what it pulls.

i don't have much power and get bad milage. i have a 40 series flowmaster on a 2000/ 3.0 automatic and it has the same power pulling a 1500 lb. boat or without. i've had a 4.0 and you can't compare them. mine is a flex fuel truck so i think it must retard timming when using flex fuel. mine may be stuck in that mode. i'm tring to find out how to check it. i may have to ask that question on here.

Further Update:
I changed the front O2 sensors and it ran rich and the mileage was not great.Before I changed the fronts I got 15MPG pulling a 2200# trailer for about 850 miles. I changed the front O2 sensors and the mileage did not really change but my truck ran really rich. I just got the Walmart Fuel injector treatment and it made a HUGE difference in power and acceleration. This thing actually responds when i step on the gas now. Even up hill. It also helped the towing ability. I enjoy driving it.
It is like a new truck and it breathes beautifully. It is not like I have a 351, but compared to what it was, it is a rocket. It feels like it operates like it should. No more 3.slow.
Here is a list of the repairs/ maintenance I did:
New cat: $300
Cat Back: $150
3 O2 Sensors $140
K&N Filter $35
MAF Cleaner $7
Throttle Body Cleaner $7
Sea Foam $6
WalMart Special $20
Each step made an improvement but the final injector cleaning was the icing on the cake. I was ready to put my old O2 sensors back in because of the truck running rich. I did not want to plug my cat.
EDIT: Forgot: changed fuel filter after 12X,000 miles, doh! It helped
