Alright I've looked around on the forum and cant seem to find an answer. I could be missing somthing though. I intsallled my dsp5 switch a couple weeks ago and I am just now getting to flash my new tunes. So I fllashed my truck and I can tell its taking a tune but it does not seem like it is switching tunes. Actually i know it is not because i have a lope tune and it def. does not switch to it. So i checked to see if my switch was working and it appears to be this is my volt. 1. NON DSP 4.98V2. DSP1 2.93V3. DSP2 1.79V4. DSP3 1.02V5. DSP4 .034V. Which the volts are going down but are not in the primeters of efi lilve data so can anyone help figure out why its not changing. I even refllashed a full flash and it still will not switch.
