Air Temp Sensor

[Bernie Benz]

Hi Paul,  Could be that the temp sensor is not lieing, but just covering
your wallet.  The 3B intercooler's heat sink capability is limited even when
new.  It's just a matter of time, how long until the charge air temp. is too
high.  Remove and inspect your IC.  Besides the usual imbedded bugs, I've
found one that was 80% plugged with sand on the cold side.
