Hemifever and Johan "Diablotoona" are the two tuners I know of for Dodge vehicles. See if you can contact either of them, you should be able to find them on the forums with a little searching. I don't know if they can help with a turbo install or not, though.

*EDIT* N/M -- The Googles show that these things are about $5,500 +/- for the 5.7L.

thanks for the reply's my buddy can get the turbo way cheaper then then $5k next question is whats a good mild cam for these engine just enough to make it chop mine has a clicking sound, sounds like rocker arm not getting enough oil or it loose that's the reason for the cam while its apart put a good cam in.

Did you put a hemi in your 02? Because factory installs weren't til mid year 03.

Don't need to change the trans (same trans, only programming difference for the extra OD gear), just the TCM depending on what year PCM you used. If you used the 04 PCM then your trans automatically became a 545.

you could have a wiring issue sound like o2 sensor is shorting and making the truck run rich which will cause the misfire or it could be the cam and crank sensor
