CAM IDOL question/concern
I recently had a cam installed in my 2015 C7. This is my first time doing a larger cam on a car and I have a couple questions/concerns. I went with a Stage 2.5 Texas Speed Cam. The car drives great and sounds great while moving. But at idol, the car can be very choppy at times. Sometimes at idol there’s a nice shake that lets you know there is a cam in the car. And I love that feeling. Then at other times there’s a much more aggressive shake that feels like an earthquake. I’ve also noticed that if my brake is not all the way to the floor at stops, my car will jump forward slightly. This also goes for when I’m ready to accel. Sometimes as I let off the brake, the car jumps forward. I’m fairly new to this. I wasn’t sure if this was due to a bad tune? Or if there could be any other issues? Or if this is just normal drivability with a larger cam in? Any insight to this would be greatly appreciated. Thanks!

This might not be the right forum for your question. You can go into the tech / performance page here on CorvetteForum or, you can go to the Gen V internal engine section at ls1tech.com. (I’ve used that forum for years for general tech questions.
You could be experiencing a tuning issue, or your cam might be decreasing the intake manifold vacuum at idle, which takes power away from your brake booster.
