anyone start beefing thiers up with cold air intake ,bully dog chips or anything like that?

The dodge hemi can make serous power, chassis dyno on car platforms can gain 50 hp with just intake and exhaust mods ( headers and cat back exhaust ) that is pretty straight forward. If you want more you are going to have to change the camshaft and computer, I am not sure if you can reprogram the factory computer. I do not know if there is a "chip" for the factory computer.

My 2004 Dodge hemi 2500 blew the front diff and the transfer case before 60,000 miles.

My 05 1500 Ram (Reg cab w/ short box) HEMI Has:

AEM cold air intake...

Super Maxx Long tube headers...

Magna Flow dual exhaust...

Super Chips Power Programer...

Runs like a bat out of hell...

Next mods will be new cam shaft with new programmer...

500 grains you're not supposed to use the 4WD on dry pavement........should'a bought a chev then you'd just have a sh*tty brakes to contend with
