Yeah let us know, I've heard the only difference is a few more deg of timing
which could also be accomplished by tweaking MTM Stage I. I tried an MTM Stage 3 for H box and was unimpressed, it made no more boost than Stage 1 either. However maybe the A box is different (if there's anything I've learned since owning 2 S4s, is the SAME chip vendor can have vastly different programming parameters between DIFFERENT model years)
