So how about the delete party everyone talks about? Sinister Diesel wants $2600 for EGR and DEF delete that includes a new stainless exhaust, 5 step tuner and a display screen.

A local company where I live offers an $1100 package that includes new stainless exhaust with just a "flash" program to delete the EGR and DEF with no tuner or display. Truck runs stock.

I guess I dont fully understand the difference.

That $2600 is pretty expensive for a delete. You don't really need to delete the EGR system, which is located in the engine bay, but you will have to delete the entire exhaust which includes the DPF filter and SCR/DEF components. You don't have to delete the DEF tank.

The difference between these two packages is one is a single tune at stock power levels(which does not need a monitor) and the other has five different power level that can be switched on the fly with a rotary DSP switch. You will need a monitor for this package since it adds power and you will need to know when to back down if your EGT's or other temps get too hot. Although I would recommend a CTS2 monitor even on stock trucks due to all the stuff you can keep track of.

I would shop around with different tuners and ask questions. Go to Duramax forums and ask questions about the tunes you are thinking about purchasing. While they will all have similar power levels, they will be different in their shift strategies and TC control. Some good companies for Duramax's are PPEI, Calibrated Power Solutions, and Anarchy diesel. There are more, but those are just off the top of my head.

I would recommend you install a pre-trubo EGT pyro(thermocouple) for your CTS2 if you are going to increase power levels. Also, buy a plug kit for all of the connectors you are disconnecting or at the very least wrap them up pretty good. The road salt up there will wreak havoc on an open connector in no time and may cause electrical issues.
