How good is the sct x3 at reading DTCs?

[20046.0]

04F350 6.0
Sct,4" straight pipe, egr, delete, coolant bypass.
278000kms.

Well in Saskatchewan it got cold tonight. (-19, -28*celcius with wind chill)
Truck doesn't have it's winter front on it yet and I have yet to change to a oil weight more suitable to winter.

My sct reads a coolant temp of 134* and it was idling for 20mins. Driving temps usually are from 165-180*. I have a edge insight on it's way from a member on the site but my truck produces more white smoke then I remembered.

Does a coolant temp that low normal? take in consideration it's very cold.

Neither one is going to be great to be honest, the EDGE will be far more useful than the SCT. Both are great for just reading codes but beyond that they are lack alot of the necessities to proper diagnose issues.......
