DSP5 Question
I have a dsp5 on my truck (lb7) and i am wanting to change the tune some on one of the settings and it isnt changing tune but if i change the same thing on my base tune it is changing there. Do i need to do a full flash or does a cal work. i know that the switch is working as i can switch tunes and notice the powere difference. Any help would be appreciated thanks.
