    Engine bogging down after shifting / torque loss

    Engine bogging down after shifting / torque loss
    Hey guys, so I am trying to get my transmission dialed in after installing a SLP 1900 blower on my 2014 silverado with the L86. I am using the trans tune I got from Diablew as my starting point because the trans tune my tuner sent me was ended up being further away from where I want to be.

    The only issue I am really having now is after the trans shifts, especially to 2nd and to 3rd, I have to significantly increase my throttle to achieve the same power as I was getting in the gear previously. I don't think it is slipping, rather, the throttle demand is lower when it gets to the next gear/RPMs drop.

    So the full tune has a transmission tune I am not using, the other one is just the trans.
