Just Bought a 97 12v :)

my truck came with glo shift guages and i may as well not even have gauges, they are IMPOSSIBLE to read during the day, put a set of sunglasses on and forget it. i have sharpie marks on the outer ring of them so i can get a general idea of where the needle is at. i moved the egt probe to the manifold right before the turbo(since it was post turbo, the readings were off) and it still reads wrong, theres no way my truck idles under 200 degrees the second i pull into the driveway before i even let it idle for a moment. they are also brand new and the face is already loose on one of them. i don't put any trust into these guages. iv got a full set of auto meters in my Chevy and they are awesome gauges, id recommend not cheeping out and just buying auto meter...
