New Truck, New To This Forum

I recently purchased a 08 2500HD Silverado with the LMM engine and still getting familiar with the truck. This is my 2nd Duramax (my other one was an LLY). When I bought this truck it had a few mods done to it already. It has a Fabtech 6" lift, AFE intake, an unknown 4" exhaust system, Edge CTS (for gauges only I can't find a box under the hood and the screen displays "New OS which is not supported). Here is my question I belive it has a EFI live tune on it because of the CTS gauge and the message it says. I also have a dial under my steering wheel with different settings from 1-5. Is this a Dsp5 switch or a boost controller? And is there anyway I can find out if it does have an EFI Live installed? I'm also interested in removing the egr and dpf system any suggestions would be greatly appreciated.

Welcome to DF. Nice looking truck. Sounds like a DSP5 switch to me. If I can ever be of assistance, don't hesitate to ask.

Take care,
