Not sure what versions I have but recently updated (last month and non meth). The 93 4+X tune is super torquey and falls off on the top end (cant hold the boost throughout the rpm). If i step down to the 93 4+ tune it feels more linear (which feels faster by seat of the pants). Definitely like the 4+ as a DD tune which feels more spirited and not so abrupt on power. Tapping into the 4+X with that torque brings in the power low & quickly but is technically faster when timed, just doesn't feel like it. If all that make sense.
If I'm not helping and completely off let me know LOL. Still learning and need the feedback. No shame here.
