Guys what have you had the best luck with for a 04 hemi?
Current set up is a K&N filter[stock air filter housing].
Cold air scoop,power wire,and flow master exhaust.

As far as a tuner I've had good results on my lightly modded '05 with the Superchips 3865 Flashpaq. It also does tranny shift schedules.

The 04 has limited trans tuning using the SC3865, if the SCT can provide trans support then that would be the way to go.

Not sure i'm ready for gears just yet...
i Do alot of highway driving across Texas.

Bill is telling you like it is. 4:56 gears are awesome.

I do not understand the why's and so-forth but, I get better gas milage with my 4:56 gears then I did with the OEM 3:92'.

Somebody out there can confirm this and possibly tell us why.:dance:

I have heard the same thing. I believe there is a 3-400rpm difference at 60mph over the 3.92. This is the only reason I am not getting the 4.56 as I do 85-90% of my driving on the highway.

How hard is to install the drop shackles?

Just looking for a more leveled stance but do not want to raise the front.
I am not set up to change gears at home what type of shops should I look at for gear changes?
With 2 guy's it took 15 min with basic hand tools to install the drop shackles.

Ask questions, like how often they have worked on the Dodge 91/4 rear end.
