From what I understand it was an issue with certain tuners base files. New base files have been sent out to the tuners having issues. I have had no problems with mine. Everything has been running top notch. Do it and don't look back.
Kick in your high idle Or just put it in neutral with the park brake on. It will run until your tank is empty. My truck is my office for 12-14 hour days and both trucks work great.
I believe you can leave the EGR in place but the exhaust has to be removed. You can get a 4" delete pipe that simply replaces a 4' section of the exhaust instead of the whole thing.
I'm not sure on the progressive steering, my truck is a fully loaded 2020 AT4 HD so if it's an option I would assume I have it?
That being said, I believe it would be worth getting even at stock height for sure. Its an affordable upgrade and makes a difference.
Just installed this kit today. I can't say I notice any more "firmness" in the steering wheel, however it is VERY noticeable how much less vibration and bump steer is reduced. I would recommend for sure, especially if you drive gravel roads and poorly maintained hiways like I do.
Just installed the RC 3+1 kit set at 2.5" in front. Replaced the rear block with a 2" block and running 295/65R20. Truck sits 42.5" floor to fender in the front and 44" floor to fender in the back. Rides better than stock IMO. No regrets and would recommend to anyone. Just have to make up my mind on wheels now...that's where I'm struggling.
