Okay to start I have a 2003 Chevy duramax, 4x4 auto. I am wanting to tune it myself, I bought both of Zach's books and I been playing around changing little thing and so on. As of right now I just was doing a single flash with the ECM. I want to do the DSP5 switch. Here's were I get a little in the dark, I am unsure what goes where when it comes to the following.
I figured out how to convert my stock file to a DSP5. I now see the following, DSP Switch, DSP Program #1-4, Valet Mode, DSP Output #1 DSP Staging And then all the of Engine Calibrations.
Here is what I am assuming please correct me if I am wrong.
Is the DSP Programs 1-4 were I would build lets say a stock tune, then a tow, fuel economy and maybe a mild race. Is the Engine calibrations were a big tune would go since there are more parameters? From the reading I have done I know there is one of them that everybody keeps saying that's where you should put your big tune in.
As far as the other settings (valet mode, DSP Output and staging) is it really anything I need to mess with? Its basically a bone stock truck other then a PPE stage 4 trans. Otherwise used as a DD. Thanks much for the help.
