"Confused Transmission" - Tuned and Downpipe

Has anyone else with a tune experienced a "confused" transmission particularly in comfort mode?

There are times where the transmission doesnt seem to know to down shift:
  • Applying more throttle, but no downshift
  • Upshifting to a corresponding low RPM in next gear ~1K RPM

Curious if anyone has experienced and if there is a fix, or i should even worry about it.

I haven't seen any posts with this issue.

How long have you had the tune? It just started doing that?

There are tune parameters for up shifts/ down shifts based on throttle percentage and RPM. I would also send Pro Freaks an email.

I have had the tune for about 4 months now... its been doing that ever since so it must be that the parameters need to be modified (didnt know for sure if that was adjustable) - I'll get in touch with them.
Thanks.

Noticing the same with mine since i've gotten a tune. Couldn't find anyone else with a similar issue until now...
