2013 6sp manual zl1 vibration?
I am having a vibration or shudder problem that I cannot figure out.
When Im rowing through the gears winding it out there are no problems, when im just cruising 50 60 mph in 5th or 6th and step on it kinda lugging the engine the car starts to shake vibrate etc...Im sure the clutch is not slipping, this just happened all of a sudden, im stumped? Any idea what I should be looking for?

The things I'd first look at is wheel balance and driveshaft.

This happen right after my battery was dead after sitting a few weeks ,maybe coincidental? So I check driveshaft, axles, etc... for any play everything seems fine.
seemed like it was a miss/shudder under load. put new plugs in and swapped out coils no change. Now I noticed when I wind out the gears with pedal to the floor I can here a slight backfire out of the exhaust, sounds like ignition problem??? Car has 4k miles on mods , cam,injector,pully's,headers, dsx fuel etc... no problems untill I had to change out my battery.

I had something similar on my SS. Check and make sure the CV axles at the hubs are tight. My left rear loosened up on me and caused some weird vibrations occasionally. Re-tightened, and good to go.

I ask because initially you mention vibrations and I took that as non power plant, but if you think the motor is stumbling which I don’t know you experience but night in day from a suspension or drive train vibration. Some people use the the battery ground for BAP and DSX, and since you changed the battery you may need to check you did not disrupt a connection.
