    2017 camaro ss a8 transmission slipping after shifts on nitrous

    Just running a 75 shot and getting some rpm flare after shifts that seems a little excessive. Do I just increase line pressures to get rid or it?

    Thanks

    Two things tend to happen with nitrous. One is there is an increase in torque that is not accounted for in the calibration, second, because the nitrous takes up air space in the engine, it can cause a decreased reading in airflow, which actually equates to a decrease in torque. Both of which need to be compensated for in the calibration, increasing line pressure in the the wot regions is one way of doing it. You need to pay close attention to where you are with torque to make sure your modifying the correct regions

    Yeah I noticed my torque is reading lower. Would raising the values in the vtt help?

    I was thinking of raising base line pressure for 1st through 5th gear by about 10% in the higher torque ranges. Would I use the tcc on or tcc off table? Or both? Or I wonder if increasing the vtt and vve table in those ranges would help.
