I am at sea level, 40 miles sand of gulf of Mexico. It is same cold start or after reaching operating temp. No way in my opinion lines can be crossed because they are sane as when I bought it and has ran like a top for several hundred miles. Rpms after warm is closer to 750, I really appreciate your experience and insight, I know gm vehicles pretty well, wanted to be a mechanic in past life and worked in garages in high school, a couple ASE classes, but this thing kicking my butt. Again your experience and help is invaluable! Thank you!
