While I have an Apexi VAFC awaiting install for tuning purposes, I'm wondering if modding my ECU, or replacing it, to provide a higher redline would:

A. be worth it
B. not destroy my stock bottom end
C. what would a safe new redline be if answer to first two questions is "yes" and "yes".

I have done zero research on this topic, as of 9:37pm, besides what little I learned when I looked into LS/VTEC a long time ago.

redline is 6500, mods below:
