Tuner help! Massive Rpm Loss when Shifting 1st-2nd????

i have a 2016 camaro ss A8
FBO e85
recently put on some 17' radials and added a 150 shot of nitrous.

got the tune, ran great and really hard! then i started having this massive shift lag shifting from 1st to 2nd gear. shift point set around 6200rpm, when launching it will almost red line, nose dive until it hits roughly 4200rpm then finally shift into second and then continue pulling hard and clean!
it only drops to about 5100rpm on the NOS.

*using a can relay from lingerfelter to initiate my NOS system.*

Could be lots of things. Share your log file. If you cannot log it yourself then you will need to bring it to someone who can log it and troubleshoot it. Probably a torque management issue.

The TCM relies on Torque Reporting from the ECM so NOS throws a monkey wrench in the system as it has no way of knowing how much torque you are actually making, result could be a fried trans.
