I thought this might be a good place to ask the following question. I have a short Isspro probe installed per the directions above. The shop that tapped it for me did it on a slight downward angle, which put the probe at an angle that made it a little on the long side to fit properly. I ended up installing a coupler to extend the fitting out a half inch so the probe would fit. Are the following temps normal at 50 degrees ambient temperature?

Idle in driveway: 270-280

Coasting down hill: 125-150

Hard acceleration up hill: 900

All these are plus or minus. Just want to see if the extra coupler is dragging the temp at the sensor down somewhat.
