So I have spent the better part of the weekend re-wiring up my LC-1. I have it on a 98' C5 w/ Dynatech Headers simulating the driver side front. I have my grounds on each head, with the heater(blue wire/heater wire) by itself on the passenger head. I had the grounds on chassis prior, but readings were all over the place. Now I'm still getting funny readings when it first starts up showing anywhere from 18.0-22.0 at idle and sometimes cruise. After 5 minutes or so of driving it settles to around 14.0 which seems correct. I've done free air cal and complete cal multiple times and still shows the 20+ on start up idle, cruise. Is this normal? Anyone have a normal looking log that I can look at, so I can figure out where I'm suppose to be?

I'm learning so please forgive my ignorance.
