storm:
I'm not sure where it's taped a shop who had done one before did mine . I know for sure the egt is taped into the down pipes, as just replaced them & had to retap the PPE's. my afr seems real accurate, atleast that what my guy & his dad said. Normally runs 14.4. Like I said love the gauges, had for about a year now, no problems except the glare & 1 color only was really looking forward to the red at night.
