coolant temperature, exhaust temperature, intake air temperature..what should these be reading on average?
 

Coolant - stock thermostat opens at 75 degC = 175 degF. I often hover around 180-185 F.
IAT will vary greatly depending on boost; the more boost the higher the IAT. The stock intercooler only has so much capacity to lower the temps. At high boost levels, I've seen 85 - 90 degF but I've heard guys says they've seen 100.
Exhaust temps again will vary by throttle position and boost. I bet some engine guys here on TY can comment. I know on the 2S engines, 1175 to 1225 was a general range. I'm not sure on 4S.
