PPEI Tuning will be offering a ECM swap for true custom tuning, which will be hard to be.
You can buy a Banks Bullet, or TS MP8.. but I would hold out for the true tuning.. if...
The overall word is, "No". But I'm not 100% sure, I know most lift and leveling kits are made for the trucks without the air suspension. Maybe someone else here can chime in

Welcome @Jambrose711 .
You're the typical truck owner, we're always wanting more power and better tires! :D
Be sure to ask any questions, the guys here would love to help out any way.
As far as tuning, good tuning that will REALLY make a difference will probably void your powertrain warranty...
Since we're growing on a daily basis, I thought now was a good time to introduce a new forum and dedicate it to wheels, tires, and general suspension questions!
I'll be moving the appropriate threads in the other forums to help keep things organized. Thanks! - Jeff
Be sure to show your truck off by adding a new garage! It's a great way to track changes of your truck over time!
