Hey bigdodge fan. Those chips are not worth it at all. Engine programmers/tuners work, chips.. nothing lol. Now for 5.7L Hemi questions, I recommend posting right HERE
as it will give you the best results. I don't know anything about an electric supercharger, but I doubt it would work too well. Tuner (Diablo sport, Superchips, Bullydog), Headers/ exhaust/ drop in filter or CAI/ torque converter/ ported throttle body (not a throttle body spacer, they are a paper weight) are generally pretty good starts. Just post a thread in the 5.7L section about what you want, and also give a rough price estimate and I am sure there will be someone who will be able to assist you.
