Please help me figure this one out. Its the last thing I need for my truck to be fully bad ass. I just finished my first 4l60e build and it shifts great and pulls hard. Only thing is, I put a looser converter in. Now when I floor it at highway speed and it drops from 4th to 2nd, it pulls throttle for a split second after the RPMs jump. It's got to be some kind of torque management. I expected to see a huge timing dip but it turned out to be a throttle dip instead. You can see it in the attached log at frame 1576. Has anyone seen this?
I have quite a few tunes now and I've been tuning my truck through many mods since the beginning of time but I haven't seen this. Please help.
