hello everyone , im new here , been reading for awhile and decided to join , lots of knowledge here. i just purchased a 2003 3500 dw 4x4, 5.9 HO 24v, mods that i know of, airdog 150, bd power turbo, afe cold air intake , copilot trans controller , and 4 " exhaust muffler only, i was told it had a chip or programm, i havent found the chip but it runs like a scalded *** ape, if i turn off the copilot it still shifts hard like it has a shift kit but not sure , how do i find out what all hase been done to this truck. who ever had this truck spent alot of money on mods so i dont think they would have skimped anywhere. thanks all

 

Is there a box or anything under the dash or hood? As far as trans you could pull of the pan and take a looksy while your there maybe tighten the bands change the the filter. Good luck.

i havent found a box or anything, was wondering if he flashed it, tans ill do that soon, thanks

 

It may be under the hood. I know my truck has a hypertech on it but its the old style where you have tocplug it in and change settings, but somehow they wired up a switch that supposedly let's.you pick the setting, I can't prove it because I can't tell a difference. But the switch is mounted on the kick panel on the right side by the floor.
