Right now im still in the process of e tuning. I currently have the VTEC set to 5100, but was thinking about dropping it back to 5000. Anything lower would probably give it a bad curve right? Also if I were to mess with the rev limits?

You should let the tuner adjust the VTEC point unless you have a dyno to verify the results.

The V6 TLX is automatic so there's not much reason to adjust rev limits at this point.
