Temp only goes about a 1/4 of the way up while driving normally. It will go to the half way mark if I go into boost (say 15psi) and stay there. It has never been past the half way mark, but I was driving it for about an hour normally without going into boost and it just stayed at the 1/4 warm mark. Would it be the sensor itself that would be causing this or maybe something else? Anyone else have this problem?
