Sorry for the stupid off subject question, but I'm new to all this tune stuff. Do we need to keep the physical device hooked up like you have in your videos ?Anyone else noticed the oil pressure shown on the ProCal is significantly different than that shown in the instrument cluster? The instrument cluster shows the reading is in PSI. The ProCal doesn’t list the measurement but not sure what it could be other than PSI. Haven’t seen any options within the ProCal to select a different measurement. At idle where the instrument cluster oil pressure is steady, the ProCal still fluctuates noticeably.
