5.7 Hemi, Cable Driven Throttle, kickdown linkage for 3 speed auto

I will also say, that much like you I was nervous about the dbw factory TB when I initially started my swap. I have been running FAST XFI for 3 yrs now, and I love the tunability of the system, but I do believe that the aftermarket stand alone ECUs will never be able to touch the extensive work that is in the factory ECUs. There are times I wish I had a factory ECU and a diablo tuner for that reason. There's way more tuners and guys upgrading hemis using that system, so they have better support in my mind. The 2003/2004 ram 5.7s ran a cable drive throttle pedal with a "bellcrank adapter" that adapted the signal to a dbw TPS signal. Modern muscle has them for sale, and I'm sure your kickdown could adapt into that box as well. I don't know if they work for the eagle 5.7, but I know they do on the early 5.7...
