I heard that if you take out a chip in the new hemi rams computer and swap it with another you can get an addition 120+ Hp. Can anyone tell me if this is the true.

I think that these chips are programable. I would doubt you could get close to 120 HP increase.

This sounds pretty unreasonable. My 03 hemi 2500 quad cab 4x4 gained more from intake and exhaust than from anything sofar. The only chip I have found is from SuperChips part # 3714. Their tests have returned 21 horse and 34 ft.lb. more torque. This is my next purchase unless somebody comes out with more power. like maybe Jetchip or Hypertech. A real nice and obtainable figure would be closer to 35 horse and 50 ft.lb. torque.
