i've almost contemplated trying to get a 2003 king ranch in the next couple of years. I just like em. and i dont need power all the time. that or a 2002 avalanche 2500. lol

 

the power is there all you have to do is give it gas.....I bet the new dodges are more powerful in 6cl mode than our 8's. If it remember correctly they are like 100hp more with less ci than our 5.9's.....the new technology coming out really is nice (as long as it works and stays working)

 

Doing the plenum fix or new intake would be a good ideal.
I don't see any mods or vehicle info profile. Are you using any after market cold air intake?

 

I ended up getting the Hughes kit w/ a 180* thermostat, new o2 sensor, and my water pump started leaking like crazy 2 days ago. Should have it all fixed after Christmas.
