H&S is for the 6.4 hands down SCT for the 6.0 nothing else touches even the preloaded tunes. With the additional options on the SCT SF3 it does what other on the fly tuners can't. I've had a Banks Six Gun and maybe power wise it was a little better. However it couldn't turn off the egr lock the converter or use the turbo vanes as a jake brake. It couldn't even change the tire size so my speedo read correctly. Plus being an on the fly tuner had so many glitches in it that I just yanked it had a new one mailed back and sold it best decision I ever made.
