Yes, I confirmed the shudder is happening when the AFM is switching between V4 and V8 modes. I want to get it disabled by sending in my PCM to LT1swap but can't really be without our second car for a week. Sadly, it will probably have to wait until my kids' 80 sports are done later in the spring when we can get by with one car.
