Kind of confused on this. Can you switch on the fly between the levels or do you have to stop and do a flash? I read the dsp5 switch thread and I wasnt quite sure about this.

When you have the dsp5 o.s you can turn the knob on the fly, your ecm will have 5 tunes within.

:exactly:

In addition, your DSP2 switch if installed becomes a Valet mode switch. In Valet mode you may limit the total amount of fuel the engine sees. Could even be used as an anti-theft device.

Thanks guys!!
