I’m having a consistent rough shift during WOT during the 2-3 shift l. I’ve been noticing the issue pretty often over the past month or so since I got my GM PERF CAI installed with dealer tune. I haven’t thought much of it because I’ve been trying to diagnose the issue- trans temps- never go above 145ish. So I decide to throw the car in tour which I rarely have it in anymore just to see what happens and sure enough every shift was smooth as butter all the way home. This is the only time I haven’t noticed the rough 2-3 shift under WOT was while I was in tour. I typically stay in sport due to tighter steering and what I believed was a more responsive and engaging rpm response. However the rough 2-3 shift makes me cringe every time and I definitely don’t think it’s great for the 10L80. Has anyone else experienced this issue after a GM PERF CAI W/tune? Or experienced this issue at all on a stock LT1 ONLY while in sport? My theory is something weird about the tune GM used didn’t flash all modes or it’s just a shit tune (very likely). Anyways I’m very inexperienced with cars in general from what I understand it almost sounds like the fuel is being cut too much during that 2-3 shift. Anyways all thoughts help. Thanks all
