Hello, I've finally gotten my car back together with all of my new parts but am struggling with vtec causing a super lean condition upon crossover and don't really know where to go from here. I've included a data log and the current calibration
thanks in advance for any help

(sorry if I've missed anything obvious or if this post is in the wrong place, this is my first time in the forums)

2010 civic si with stock internals
mod list:
RDX injectors
hybrid racing CAI
Skunk2 Alpha headers
Skunk2 MegaPower r catback
lightweight flywheel (8.9lbs)

Have you added fuel to the table right before it switches into the VTEC tables?

I'm sorry i have taken so long to reply to this, turns out a wheel speed sensor was starting to go out and it was doing all sorts of weird things but adding some fuel all around the switch point did help smooth things out significantly :)
thanks for the help!
