low RPM shudder and loss of power I know its a horse that been beaten so badly it can't walk but here's my issue. I've got a pretty stout LT1 and its strong however around 1500 rpm it gets a shudder and it lasts until about 2000 rpm. During this time the exhaust tone changes and I lose power. I know its not the opti as I just replaced the 2 year old accel junk and the water pump that crapped out. The icm and coil are new. The egr is new. The plugs and wires are new as well. Has anyone had this issue and fixed it or am I looking at something caused by the cam? Just to cover my bases the tranny and torque converter are new and have been checked as well. I'm just stumped....
