E brake feel after rough country lift installed

I had a rough country 3/2 lift installed today and it feels like the emergency brake may be applied. I have 0 idle and it moves slowly when I accelerate. Anyone has any answers. I will be briginng it in tomorrow morning. I'm just looking for advice so I can sleep tonight.

 

It's a truck, not a sick loved one. Go to sleep.

Let the installer correct their problem tomorrow.

 

Touché. I'm having to miss some work for it. So I was looking for early suggestions to throw at them.

 

Just accurately describe what it's doing, and replicate it with them in the vehicle.

It's their job to figure out why and correct it.

 

Just wondering if you got humongo wheels/tires installed along with the lift, and the resulting effective gear change and added unsprung weight created the feel?

Or if it was lift alone, what the resolution was ????????
