MODS feel free to direct me to the correct write-up thread and delete this one if needed. I'm having a hard time finding any info on this.


I am trying to change the 5th position on DSP5 tuning to make it hiss at idle.

I thought the tables I needed to change were Engine Operation > Turbo > Position
-I am editing 600-1200 RPMs and 0-20 MM3s


Client's truck has a goofy inline device connected to the OBD2 port and I'm not sure if it's disabling my changes I'm making with the tune. Any help is appreciated. TIA guys
