It might work well for bone stock cars, but once you start modifying your car, it will clearly be very off. I actually discovered this by installing a giant oil cooler only to read the same temps. Then I read a posting about how these are calculated estimates. In short, to see your real oil temp, you need an oil temp gauge. Apparently, GM has real readings only in dry-sump models like LS7, etc.
Yup, DIC readout is a joke, 266 every time. The 2SS gauge cluster does seem more accurate.
