Motor noise coming from middle of motor, comes on strong after a run on the Edge Programmer (Stage 5). Checked it all over and I can't figure it out at all. Lifter?

Do a search for the "tick tick tick". Its normal....lots of dmaxs do it....including mine. Mine comes and goes....there was a TSB out a while back from GM explaing the noise....it might come up in the search.

this is NOT an emergency
