Intake design for stock appearing class and needed a winter project

12.5, the meter is new from first of the year. Had another meter that was temp install thing a friend is using. Plus I wanted a permanent/clean installed one. Thinking about it I calibrated it on install in the garage. At like 70 degrees. I’m going to check it again at idle and recalibrate it. See how much it changes the idle reading from the original calibration.
