I've never seen this before, and I'm truly baffled.
This is a car I'm remotely helping somebody with. It is just a simple cam setup with a built 6L80. The trans does great now, but I asked the guy to do some WOT runs to finish setting up the shift points at WOT, and he sent me the following log from a dead swap.
I cannot find anything in the tune that'd be limiting the blade to ~53%. Anybody have any suggestions? I'm sure it's something simple I'm overlooking, but this is driving me nuts.
