Reduced power and P2101 code
I've had 2 instances where my car (stock other than a Solar TB) has went into reduced power mode. This time I was able to get a code reader on it and the P2101 came up.
I live at about 4K above sea level, and both times the code has happened was at sea level. Both times driving on the highway with low RPM's.
Does the collective think this could be related to the SolarTB and possibly a drastic difference in elevation? Would this be a symptom of having a leak as in I didn't get the screws tight enough on install? I know it may not be related to the TB also, so open for any ideas.
Thanks for any input in advance.

That is a common code for max effort ported throttle bodies. You can easily tune that out in HPTuners. But if you don't want to tune, you can either try the throttle relearn procedure or ask the seller to exchange for a less aggressive version.

My Z06 did the same. Contacted Soler and they sent me new TB the next day. Appears to be a common anomaly. So far the replacement has been trouble free.

If the full relearn doesn't help I'll try that route.
